Uncle Doug, Every once in a while we all meet a person who sets the benchmark for what a man should be. You are that benchmark Doug. Thank you so much for sharing with us!
Hi Doug, i have a 1997 Fender Twin amp, i was wanting to have it looked over and possibly fixed as far as Capacitors go and all,how do i contact you for service? It has a pcb board setup, would you think it would need to be “Re capped”? Do Capacitors wear out after so long? The amp has barely been run
@@historiclp4577 1997 sounds recent , most re-caps are on 1960s and earlier, maybe some 70s gear. But the packing inside can fail with getting a voltage after long out of use, only replace that which does not pass reasonable tests as shown on other UD videos.
@@historiclp4577 Gino, I appreciate your desire to improve your amp, but I don't work on modern equipment, especially with PCB's. If it's working fine, with no hum or other problems, I would simply use it until something does occur.....if it ever does. Good luck.
@@historiclp4577 I would be more concrened if the amp was made in the early 2000's when a bad electrolyte batch in the Far East turned into a plague of bad capacitors.
When I watch your work, the word that comes to mind is "precision." We live in a world, where a slapdash approach appears to be condoned if not even fostered- whether it be in spelling, grammar, and a whole host of areas of life where it was once alien and rooted out. On that basis, doing a bad or sloppy job is the standard for so many- a "take the money and run" attitude. It is a real delight to see someone putting pride in the job at the top of the list and delivering on this- not least in a situation where somebody's life may be at risk if something is done badly or with a less than diligent approach.
After having watched most of your videos I can say that you are by far the best thing on RUclips for vintage amp electronic repair. I love your sense of humor and clear, concise way. A true national treasure! Thanks and please keep 'em coming Uncle Doug (and Jack!)
@@UncleDoug I had a good ol belly laugh on that statement. and reminded my of my youth. While attending HS in ElPaso (go Rockets), I was curious(and 17) and drove my dad's van to one of the red-light districts in Juarez with my stepbrother. We parked and were immediately approached by a guy selling "real" diamond rings. He followed us down the road while dropping the price with every other step. He "proved" the authenticity of this incredible gem by scratching the windshields of several cars. "look - real diamond man - scratch - gouge". We passed on the deal of the century and decided we better leave or risk the windshield of the van to be used as his new favorite demonstration vehicle. I later learned that it was customary to pay local kids to watch the car. Later still, I was told they wouldn't actually prevent anything from happening to it, but you did get an exuberant account of what happened with full descriptions of the bad guys that could describe 99% of the native male population. They, of course, would still expect to be paid the final 1/2 have of the negotiated "watch" fee.
Theres a JJ Cale song, "Tijuana": "Just below/San Diego/ Tijuana/ land of broken dreams/.....Senoritas/ dancing in the moonlight/ flashing Spanish dark eyes/ at everyone it seems.....they say ' hey gringo/ won't you take me across the border?/ tell 'em I'm your daughter'......". David Lindley plays this song beautifully on acoustic lap steel.

Bless you Uncle Doug, for sharing your wisdom with us. Just a great educational video. Your videos make us feel young again. Thank you for saving our guitar tube amp history.
All my teenage memories flood back as I see so many amps from my era come alive. I played bass and was taught a bit of guitar as I took bass lessons and can play so many of the songs you do on your show. Thanks

Great work! One day I'll get as clean at my work as you! I built my first amp over the summer, and I decided to be ambitious and build a 6G6-B and do some additions and modifications including a reverb circuit, a dual rectifier, a switchable additional gain stage and bright switch on the normal channel, a deep switch on the bass channel, and a NFB bypass switch. It's a tone beast! I couldn't have done it without your videos! You may know this, but the Blonde Bassman was Paul McCartney's primary bass amp for most of the original Beatles recordings, and on the later albums, they would fight over who could use it. After the Beatles broke up, George Harrison used it for years. I'm amazed that someone found one at a yard sale!
My birthday the 6th March. Only just noticed the date after watching 3 times. The Knowledge i have gleaned off of you Doug has been invaluable. Thanks UD.
I"d like to nominate "Uncle Doug" for this years "Leo Award" for best comprehensive and outstanding video in electronics amplification , and "Jack" for best supporting assistant!!! Many thanks and appreciation!!!!
Great to see that you ended up getting the resto job on this classic amp Uncle Doug, no one else would do it justice. I bet that Jack & Ollie are excited too
I love your humor, Doug. I never laughed so hard as when you suggested keeping that original power cord or that the standby switch has to be broken since the power switch is. Always a joy to watch you repair an amp, especially something as vintage as this old Fender.
Oh yes! Uncle Doug on a '61 Bassman! A great start in the weekend. What a great piece of music gear put back to life by my favourite technician. Fantastic!
I take notes as you talk, on all of your videos Ive watched so far, it helps me retain knowledge better. You have taught me so much and I just want to say Thank You Uncle Doug.
Doug, I just want to thank you for posting some of the best instructional videos on RUclips. Your series on building a Fender style cabinet from scratch and applying the Tolex/Non-Tolex covering is second to none. I have studied many others and your's is the best. Keep safe my friend, wishing you and your's the best .Peace.
I was watching your old Fender Twin from Hell video (the ass-kicker) when I got the notification for this, another big old Fender. Happy days! I'm just waiting for incoming funds before pulling the trigger on a '66 Blackface Champ that needs a little TLC, that I'm going to do myself, thanks to your videos, Doug. I ended up doing the US Navy's NEETS course on electrical engineering, and have got myself a basic lab setup, although I still want a 'scope. Anyway, I just wanted to give due props to the maker of some of the most educational content on RUclips, cheers, Doug!
I have a 1962 Bassman Head that belonged to Warren Flock, who briefly played with Eddie Cochran. I bought it from his son. Had it freshened up, much like what Doug is doing with this amp. I have found it to be one of the most spectacular amps I own. While I've had this amp for many years I've found it loves different cabs and speakers. Example; Vox Sovereign 4X12 with 2 Vox Blues and 2 JBL D120F speakers. I had no idea how good an amp can sound until I tried this combination. This is just the tip of the iceberg. Try other cabs and speakers! Stunningly beautiful. Thank you Doug!
The audio demonstration was awesome ! I listened to it three time in a row. The composition was some of my favorites ! Learning lots. Thank you so much, Doug !
If you ever make t-shirts, you should have an image of a schematic and a tube with the caption "I Dig Doug". I'd buy at least three. Just a suggestion.
I worked in electronics for over 40 years and even knowing how those components work, it still seems like magic to control, block, resist, and direct the current flow and come out with such a beautiful sound. We used to call this FM. Great work and I appreciate your attention to detail. Who will know? You will know and the next guy will know.
These older cloth-wire amps have quite a few wire runs hidden underneath the circuit board, the later ones have all the wire runs on top the board, instantly messier, plus the circuits got more complex.
@@jothanankrogh , I've "black-faced" some silverface Fenders, so I'm aware of the jumpers under the boards, the increasing complexity of the circuits, and so on. Adding tremolo and/or reverb certainly increased the mess under the hood! Still, the build quality of the CBS-era amps devolved pretty quickly compared to their predecessors.
@@goodun2974 my biggest problem with the CBS methods seems to be the wax coatings causing conductivity of the boards. In the preamp areas, conductivity between the plate resistor eyelets and the nearby tone stack capacitors eyelets, causing DC to show up on the volume and tone pots, lotta noise.
@@jothanankrogh , that's the one major failing of Fender amps ---- they should have used phenolic boards, especially the type with turret posts. PS, I don't know what kind of wax they used, but I do know that beeswax is hygroscopic and absorbs moisture. I don't know if that also applies to paraffin wax.
I just decided to go back and rewatch this. I really hope I’m not alone in this, but I honestly think the 6g6b is probably one of the best sounding circuits. I think it’s way ahead of its black face and newer counterparts. Thank you again Uncle Doug. You and your channel are an amazing wealth of knowledge and humor l.
This is as good as it gets! The highest level of repair on the highest level of amps... this is like fine art! Thanks uncle Doug for this literally wonderful video!
WOW that amp has a soul, sounds fab the sound takes me back to the days of my youth 60s 70s, Great job uncle Doug and thank you so much for sharing your incredible knowledge, great sounds.Cheers. Andy.
Truly Enjoyable to watch! A total drool worthy Fender amp ... From one 1961 blonde, (me!) to another, I wish this awesome amp, another 6 decades of life!
B ad B oys R ape O ur Y oung G irls B ut V iolet G ives W illingly ( G et S ome N ow) Some things you always remember. Plus a 50 watt Bassman is one of the best guitar amps Fender built.
Your videos are a much needed and very educational distraction. I work in a grocery store in ground zero (Seattle area) and I can use all the educational distraction i can get.
Deoxit > other stuff. I learned this directly. Had a scratchy pot and didn't want to spend a ton on Deoxit so I bought some electronics cleaner from the auto parts store. Nope. No change. Still had a scratchy pot. Over a year later, I finally decided to buy a can of Deoxit. Sprayed the pot, worked it a few times and it was completely quiet. No more scratchy. That's all I needed to see to understand why Deoxit is better and costs more than the $3 can at the Auto Parts Store. Being an automotive tech & mechanic like you, Uncle Doug, I should've known that there was a reason Deoxit is 5x the price and why everyone praises it. It's a tool that works. In the automotive field, when you have a tool that makes the job that much easier, you buy it and don't worry about the cost. I should've known. I'll know next time. Kind of like the StewMac Z-file fret crowning file. I paid $92 for it but it's going to allow me to do $2100 worth of work to my 7 guitars. Being able to level & crown the frets myself is going to save me sooooo much money. Thankfully most of my guitars were leveled and crowned at the factory so there's only a couple of frets on each one that need dressing. Enough that I could do them 1 by 1 instead of a full level and dress and save some height on my frets by not filing them all down when only 2 need work.
I agree that Deoxit is a very effective chemical, J. My only complaint is the aerosol delivery system is inefficient, tends to leak and fail, and wastes a lot of expensive product. I also agree that quality tools often facilitate quality work.
I, can't tell you how grateful I am that I found the guitar community on RUclips. It led to me buying my first guitar, first amp, and first tube amp. It's about 90% of a Marshall circuit from what I understand. A Laney Cub 12R with a spring reverb. I knew I was supposed to be a musician from a fairly early age. I just never went for it because I was strung out on drugs from 15 to 30 years old. It took me another 7 or 8 years to realize the things I liked. Hobbies, etc... And since I actually had money in my pocket instead of drugs up my nose, I could buy guitars and amps and pedals and tools and things to build pedals and amps and guitars lol. So glad I got clean. I wouldn't be playing today if I hadn't. I just wish I had started early in life. I'm sure I'd be an, incredible player now. Oh well. I'm having fun again and that's all I care about. After the death of my daughter and only child in 2014, there was no more joy. Playing guitar is the first time I've experienced genuine joy since the death of my child. I'll never quit playing. I'll never sell my gear. Never. I feel like my life depends on it. Same goes for my dogs. They're a huge part of why I'm still here and haven't checked out. So I won't ever be without a dog for the rest of my life. They are that important to my well-being. Just like my guitars.
Wow....Thanks for sharing this with us, JC. Congratulations on regaining control of your life and focusing on the best things in life: like good music and dogs ;)
Your attention to detail is second to none! Digging through all the different versions of the schematics to find improvements is something most repair techs (in any field) just don't do. Outstanding work!
Hello Uncle Doug & Family, Kitties too, It pretty much goes without saying, that, you are the tube amp master. Beautiful repair and sounding oh so good. Olie and Jack have been practicing! The song 'One' by U2 is really easy and a good song. Good gravy, pulling a few G's in that little Rambler! Thank you, C.
incredible find & great video. my introduction to the entire Bassman "thing" was thru a cheap clone called the MIG-50. i took it into a room, turned it up to 8, and was just floored. i'm a bassman guy ever since. incredible amps
Hi Uncle Doug. I want to tell you about a little trick that's almost always used when connecting a potentiometer like a rheostat, i.e., when you use only the wiper and one end of the pot, as you did when installing the bias-adjust pot. The trick is to directly short the unused end of the pot to the wiper with a short piece of wire. If you think about it for a bit, you'll realize that under normal operation, it doesn't change anything. However, in the case where the wiper loses contact, either momentarily or permanently, with the resistive strip, instead of the resistance going to infinity, it goes to the full value of the pot. Sometimes, this difference in behavior can save a circuit from damage, and sometimes it just makes the pot quieter if the pot is a bit dirty. This is just a little, zero-cost bit of sophistication in circuit design.
"Drunken chimpanzees"? LOL! I spit out my tea when you said that. This resurrection was enlightening. I knew there were differences when Fender began using solid state rectification; but not to the extent you demonstrated. It now makes sense, tonally. Despite the improved input integrity. I did search my parts boxes for the requested items, but it proved fruitless. The switch to the normal channel toward the end of the audio test woke my ears completely. The tone was vintage sparkle, and reminded me of my old Bandmaster. A million thanks for sharing this renaissance of the Blonde Bass Man. Enjoy what's left of the weekend, dear uncle.
I love working on these old point to point wired amps. There are very few things that make them unfixable. No matter how rough they may seem there is gold there.
Uncle Doug, I would like to sincerely thank you for creating this fantastic channel. You are a fountain of knowledge, a generous and gifted teacher and a welcome respite for me during the past year. You see, last may my lovely wife was diagnosed with a rare form of cancer and she is sadly in stage 4 with that cancer. I've had to quit my job as a zookeeper, which I loved, to take care of her and she goes through surgeries and chemo.I'm glad to do it, but it's hard in many ways. I play guitar when I feel inspired, but about the only thing that I have enjoyed lately, has been learning how to repair and build tube amps.You. are responsible for the majority of that enjoyment, interest and the confidence that comes with the knowledge of knowing that I'm learning from the best. Sorry for the long and personal note. Thank you.
Thank you for this wonderful note, Greg, and for your very kind comments. If our efforts have provided you inspiration and distraction during this difficult period, we are sincerely glad.....and we wish you and your wife the very best for a speedy and complete recovery. Please keep us informed of her progress, and by all means, please continue to watch and enjoy our channel.
@@UncleDoug It's an honor to hear from you. Thank you so much for your words of support and kind wishes.. Our next step in her cancer treatment is to go to San Diego for another surgery and HIPEC chemo treatment. The cancer is so rare that there are no specialists in Northern California. When we return, and when I have some free tlme, I look forward to finishing my first full amp build, a 59 tweed style 4 x 10 Bassman. Then I'd like to go over/restore my old Marshall JMP. Until then, I will have a week or two while we're in the hospital to binge watch the remainder of your fine videos. Best regards and keep up the great work.
@@gregmenacho7667 Thanks for the update, Greg. I and our entire YT family send our best wishes to you and your wife for a speedy and complete recovery. Hopefully you will both be home soon, and you can resume working on your Bassman project.
I hope you are keeping yourself safe during these difficult times. Stuck at home myself revisiting some of your old work. Excellent stuff. Keep the videos coming. Kind regards.
My ears seems to be drawn to the Fender 6G circuits, with this one being my favorite. I've been watching and re-watching your vids and have learned a ton. Thanks so much for doing these. The content is invaluable, and I'm truly grateful for all you've done on this channel.
And must add yes quality of the craftsmanship is very important myself as well since by the day as I call it my hobby is a mechanic working on old excavating machines and forklifts detail to detail down to wiring and those capacitors look fantastic....
Thanks for the comments on tube heater wiring. I'll be building a home brew stereo amp- nothing special, just a little 10WPC with 6AQ5s since I had a pair of CVP1s. I knew to twist the wires, but kits that I had built over the years had me tucking them down by the chassis.
Uncle Doug, you are a national treasure, your teaching will inspire a new generation. I would love it if your get Jack and Ollie to turn it up a bit and blow the lid of of the joint. That Bassman amp is capable of some serious mischief. Of course the neighbors will complain, and call the cops. That is the price of rock and roll. Who needs distortion or overdrive pedals? That amp can make some serious decibel levels. Let it rip.
Thanks so much, Michael. To be honest, the amp is routinely set right at the threshold of pain for us making the audio demo. The microphone and recording gear tend to moderate the volume down to a tolerable level. Even if we ran the amp at 10, the recorded volume would still be about the same.....and we would be deaf.
@@UncleDoug I understand, in my opinion there is nothing sweeter than the pure tone of a well amplified instrument. I do enjoy the sound of a guitar. But the amplifier has the power and the ability to add another dimension. Not just roar and rumble, but a real singing feedback that can be manipulated by the player. That is what distinguishes one amp from another. A Fender has a signature tone, that is different from and Ampeg or a Gibson or a Valco. If you wish to get pure clean tone, then the solid state amps are the way to go. With vacuum tubes there is a transfer of electrons across a distance that can not be duplicated in any other way than in a bottle. And that is why we love them.
@@UncleDoug Thank you for the kind reply, you are a gentleman and a scholar. I was thinking about your hot rod cars. Back in the day the drag races were big, but outlawed. In Philly we had the meadows and Decatur road, which were back roads with good asphalt and a sweet 1/2 mile strip. Every weekend the racers would assemble to try their latest jazzed up hotrod. Some great races. Also some wild crashes. The cops would bust it up every so often. Your interest in hot rods and tube amps is interesting. And my point about pushing the tube amps is similar to hotrods. You do not build a street rod to cruise along at 55mph. And if you have a guitar and an amp, you crank it up and see what it can do. Turn the amp up to ten and control it with the guitar.
So glad to see a lovely blonde Bassman come back from the dead!!! Always enjoy your videos Uncle Doug. A while back you answered some questions I had about stripping paint off of my 62 Bassman head. Your advice was very useful and much appreciated. The amp looks and sounds great and am so glad your were able to help another Bassman get back to their former glory! All the best.
Im 78 years young and been a musician all my life and We used to in the old days call that little silver box mounted on the chasis of all the fender amps in those days the suicide box because if you were into repairing your own equipment as most of us were then you learned really fast to put the cover back on that thing when you were done diagnosing and repairing in there because if you were to accidently touch something in there you immediately realized how much voltage was going thru it
"It's a reflection of the care you took, while working on the amp circuit".. thanks for doing it this way! a few years back, i've seen a documentary about the Aston Martin one-77 and they have highest quality standards even at spots that you would never see (most likely not even a mechanic), but they claimed that only this reflects the overall quality and craftsmanship that the buyers deserve.. i think you have the same understanding of what's "quality work"
@@UncleDoug i wish everybody was like this! Then we'd still have electronics that last 50 years or more, and are still repairable, unlike a lot of devices today that are built to last until the warranty is over to ensure recurring revenue for the manufacturer..
I just picked up a silver face '70s bassman 50 ,beautiful condition ,it sounds fantastic with a bass and somebody properly added a master volume, it's one of the best bassmans that I've ever played through and I've had quite a few and I play bass through these things, very inspirational video 🙏🏼🎵🎵
Another gem saved from the junk pile by the Master, Uncle Doug. I just love how you explain technical jargon and best practices so well...you never insult your audience and take a natural assumption we don't know. Example, how to properly wire the AC to the heaters with such twist and care to "drop them down," while elaborating that the DC wires laying around the chassis aren't as susceptible. I wish I had an electronics course instructor as patient and well-vocalized as you. Please keep the videos coming, we all appreciate them.
Man, I need to take a course in amp building, your videos are SO damn cool uncle D. I'm jealous of your knowledge and skill. You also prevent people from making mistakes that will prevent hours of extra work. Again, much respect.
Thank you for another wonderful video and you are such a good teacher. The Desoto Fire Flite is coming along nicely. It's going in for a custom "sewer pipe exhaust" next week.
What a Swiss Army Tone Knife Monster of a Beast! Me and my buddy Sam Adams will ride the storm out. You out did yourself on this one. Primo. Sometimes I get sobered up and tuned up mixed up... And our buddy David is a good egg ;)
You've done a valuable service to all aficionados by documenting original builds for reference. This isn't going to collect dust unused in a museum, it needs to work reliably. I bet Leo would do no less.
I really enjoy watching old electronics repaired correctly. I'm worried that there aren't enough young people replacing the older guys. There are so many fields this is happening in. Guess that's just the way it is.
I'm pleased to report that quite a few viewers are both young and interested in tube circuitry, Michael. Who knows, maybe this won't be a lost art after all :)
I did a similar rebuild on a 59 tweed bassman '5f6-A, except I left it fixed bias. Got a beautiful cabinet from Rodgers Amplifiers before he retired. Great sounding amp. Say hey to Jack for me.
Dear Uncle Doug, Just another fine job on this vintage amplifier, sounds so good through my headphones, what a great job... You are one of a kind, keep these videos coming.... sounds so good, I could listen for hours...
Hi Uncle, I haven't been watching your vids the past 3 weeks, but I just passed by to say that by all means stay healthy, and that I wish you and your family patience and good luck during this hard times. I'll be back soon, cheers.

It's an ailment that causes a lot of extra work.....but great satisfaction when the customer is very, very pleased.
"sufferers from integrity".. I like that phrase! It describes some situations I have seen as well!
All my teenage memories flood back as I see so many amps from my era come alive. I played bass and was taught a bit of guitar as I took bass lessons and can play so many of the songs you do on your show. Thanks
These vintage tube amps do conjure up a lot of great teenage memories, Doug. I guess that's one more reason to love them.
What a lovely sounding amp! Thanks for sharing the restoration!
Really cool watching you take an old beat up amp from the scrap heap and making it function well again. Thanks, Uncle Doug, love the posts.
It was our pleasure, BW :)

Great work! One day I'll get as clean at my work as you! I built my first amp over the summer, and I decided to be ambitious and build a 6G6-B and do some additions and modifications including a reverb circuit, a dual rectifier, a switchable additional gain stage and bright switch on the normal channel, a deep switch on the bass channel, and a NFB bypass switch. It's a tone beast! I couldn't have done it without your videos!
You may know this, but the Blonde Bassman was Paul McCartney's primary bass amp for most of the original Beatles recordings, and on the later albums, they would fight over who could use it. After the Beatles broke up, George Harrison used it for years. I'm amazed that someone found one at a yard sale!
Watching you bring that gem back to life was just amazing! And the sound! Damn! Thank you Uncle Doug!
Thanks for watching, LB :)
My birthday the 6th March. Only just noticed the date after watching 3 times. The Knowledge i have gleaned off of you Doug has been invaluable. Thanks UD.
Glad to hear it, CF. Thanks for watching :)
I"d like to nominate "Uncle Doug" for this years "Leo Award" for best comprehensive and outstanding video in electronics amplification , and "Jack" for best supporting assistant!!! Many thanks and appreciation!!!!
Wow, RG. Jack and I gratefully accept your nomination and hope that it comes with lots of beer and steaks ;)
Nice to see Mr Jack in perfect shape ! Great revival of this Bassman beauty !
Thanks twice, JB :)
Great to see that you ended up getting the resto job on this classic amp Uncle Doug, no one else would do it justice. I bet that Jack & Ollie are excited too
Thanks, Pedro. They were indeed :)
These videos are getting me through isolation. Watching a master work is so peaceful.
That's good to hear, Don. We're here for you :) Be sure to subscribe to get new video alerts.
I love your humor, Doug. I never laughed so hard as when you suggested keeping that original power cord or that the standby switch has to be broken since the power switch is. Always a joy to watch you repair an amp, especially something as vintage as this old Fender.
Thanks, Ronny. I'm glad you enjoyed it.
Oh yes! Uncle Doug on a '61 Bassman! A great start in the weekend. What a great piece of music gear put back to life by my favourite technician. Fantastic!
Thanks so much, Oliver :)
Giving the video's on this channel a thumbs up prior to seeing them is becoming standard practice for me. Great job! :)
Thanks, Berre. We hope to be worthy of your trust.
I take notes as you talk, on all of your videos Ive watched so far, it helps me retain knowledge better. You have taught me so much and I just want to say Thank You Uncle Doug.
You're quite welcome, Brian. We really appreciate it :)
Because sometimes words don’t do it justice.👍👍👍👍👍👍👍👍
Doug, I just want to thank you for posting some of the best instructional videos on RUclips. Your series on building a Fender style cabinet from scratch and applying the Tolex/Non-Tolex covering is second to none. I have studied many others and your's is the best. Keep safe my friend, wishing you and your's the best .Peace.
Wow, thanks so much, Anthony. Likewise on the good wishes.
Early Sunday morning. Family still in their beds. A cup of coffee and an Uncle Doug video to watch. Can it get any better?
Thanks for your insights, easy descriptions and most of all the demystifying electronic circuits on the whole. for us simple minds.
I was watching your old Fender Twin from Hell video (the ass-kicker) when I got the notification for this, another big old Fender. Happy days! I'm just waiting for incoming funds before pulling the trigger on a '66 Blackface Champ that needs a little TLC, that I'm going to do myself, thanks to your videos, Doug. I ended up doing the US Navy's NEETS course on electrical engineering, and have got myself a basic lab setup, although I still want a 'scope. Anyway, I just wanted to give due props to the maker of some of the most educational content on RUclips, cheers, Doug!
Thanks so much, Gerry. Best of luck with your Champ project.
I have a 1962 Bassman Head that belonged to Warren Flock, who briefly played with Eddie Cochran. I bought it from his son. Had it freshened up, much like what Doug is doing with this amp. I have found it to be one of the most spectacular amps I own. While I've had this amp for many years I've found it loves different cabs and speakers. Example; Vox Sovereign 4X12 with 2 Vox Blues and 2 JBL D120F speakers. I had no idea how good an amp can sound until I tried this combination. This is just the tip of the iceberg. Try other cabs and speakers! Stunningly beautiful. Thank you Doug!
That amp sounded awesome....as did that car's engine. Zowie
The audio demonstration was awesome ! I listened to it three time in a row. The composition was some of my favorites ! Learning lots. Thank you so much, Doug !
Glad you enjoyed it, J. You're welcome.
If you ever make t-shirts, you should have an image of a schematic and a tube with the caption "I Dig Doug". I'd buy at least three. Just a suggestion.
Thanks, B55. We'll keep that in mind :)
I worked in electronics for over 40 years and even knowing how those components work, it still seems like magic to control, block, resist, and direct the current flow and come out with such a beautiful sound. We used to call this FM. Great work and I appreciate your attention to detail. Who will know? You will know and the next guy will know.
Look how neat the interior wiring of a pre-CBS amp is; then compare it to a CBS era Fender amp.
These older cloth-wire amps have quite a few wire runs hidden underneath the circuit board, the later ones have all the wire runs on top the board, instantly messier, plus the circuits got more complex.
@@jothanankrogh , I've "black-faced" some silverface Fenders, so I'm aware of the jumpers under the boards, the increasing complexity of the circuits, and so on. Adding tremolo and/or reverb certainly increased the mess under the hood! Still, the build quality of the CBS-era amps devolved pretty quickly compared to their predecessors.
@@goodun2974 my biggest problem with the CBS methods seems to be the wax coatings causing conductivity of the boards. In the preamp areas, conductivity between the plate resistor eyelets and the nearby tone stack capacitors eyelets, causing DC to show up on the volume and tone pots, lotta noise.
@@jothanankrogh , that's the one major failing of Fender amps ---- they should have used phenolic boards, especially the type with turret posts. PS, I don't know what kind of wax they used, but I do know that beeswax is hygroscopic and absorbs moisture. I don't know if that also applies to paraffin wax.
Bad Ass man!!!!! You just helped to demystify the last 40 yrs of my life.
👍👍👍👍
That was our goal, Michael :)
Dang, what a sweet sounding amp. As the late Robin Williams famously said, "Sell my clothes Marlene. I think I've died and gone to Heaven."
Wow.....thanks, TM :)
I just decided to go back and rewatch this. I really hope I’m not alone in this, but I honestly think the 6g6b is probably one of the best sounding circuits. I think it’s way ahead of its black face and newer counterparts. Thank you again Uncle Doug. You and your channel are an amazing wealth of knowledge and humor l.
We're glad the video was helpful, Aaron.
I rewatch Dougs videos all the time. I second the compliment to Doug and his great work.
Hi Doug, I’ve got a theme song for your Nash Rambler. “Beep Beep” the 1958 offering by The Playmates. Great vid as always!!!
Thanks, DB. The perfect tune :)
While driving in my Cadillac... :-)
@@tom7601 "Beep....beep"
Uncle Doug: His horn went Beep, Beep, Beep...
"Hey buddy, how do you get this amp ... out of second gear????!!"
This is as good as it gets! The highest level of repair on the highest level of amps... this is like fine art! Thanks uncle Doug for this literally wonderful video!
Thanks so much, Grant :)
Not exactly stock?
You have redefined understatement.
WOW that amp has a soul, sounds fab the sound takes me back to the days of my youth 60s 70s, Great job uncle Doug and thank you so much for sharing your incredible knowledge, great sounds.Cheers. Andy.
Thanks so much, Andy.

Some things you always remember. Plus a 50 watt Bassman is one of the best guitar amps Fender built.
That was the same non-PC resistor code that my high school electronics class teacher taught me in the early 1970's!
Boy, this mnemonic would go over well at a feminist's convention ;) Thanks, Carl.
@@UncleDoug yeah times were a lot different when I was taught that. I think they even still taught home economics and shop classes too.
Your videos are a much needed and very educational distraction. I work in a grocery store in ground zero (Seattle area) and I can use all the educational distraction i can get.
Thanks, Jeremy. Stay healthy !!
Deoxit > other stuff. I learned this directly. Had a scratchy pot and didn't want to spend a ton on Deoxit so I bought some electronics cleaner from the auto parts store. Nope. No change. Still had a scratchy pot.
Over a year later, I finally decided to buy a can of Deoxit. Sprayed the pot, worked it a few times and it was completely quiet. No more scratchy. That's all I needed to see to understand why Deoxit is better and costs more than the $3 can at the Auto Parts Store. Being an automotive tech & mechanic like you, Uncle Doug, I should've known that there was a reason Deoxit is 5x the price and why everyone praises it. It's a tool that works. In the automotive field, when you have a tool that makes the job that much easier, you buy it and don't worry about the cost. I should've known. I'll know next time.
Kind of like the StewMac Z-file fret crowning file. I paid $92 for it but it's going to allow me to do $2100 worth of work to my 7 guitars. Being able to level & crown the frets myself is going to save me sooooo much money. Thankfully most of my guitars were leveled and crowned at the factory so there's only a couple of frets on each one that need dressing. Enough that I could do them 1 by 1 instead of a full level and dress and save some height on my frets by not filing them all down when only 2 need work.
I agree that Deoxit is a very effective chemical, J. My only complaint is the aerosol delivery system is inefficient, tends to leak and fail, and wastes a lot of expensive product. I also agree that quality tools often facilitate quality work.
I, can't tell you how grateful I am that I found the guitar community on RUclips. It led to me buying my first guitar, first amp, and first tube amp. It's about 90% of a Marshall circuit from what I understand. A Laney Cub 12R with a spring reverb.
I knew I was supposed to be a musician from a fairly early age. I just never went for it because I was strung out on drugs from 15 to 30 years old. It took me another 7 or 8 years to realize the things I liked. Hobbies, etc... And since I actually had money in my pocket instead of drugs up my nose, I could buy guitars and amps and pedals and tools and things to build pedals and amps and guitars lol.
So glad I got clean. I wouldn't be playing today if I hadn't. I just wish I had started early in life. I'm sure I'd be an, incredible player now. Oh well. I'm having fun again and that's all I care about.
After the death of my daughter and only child in 2014, there was no more joy. Playing guitar is the first time I've experienced genuine joy since the death of my child. I'll never quit playing. I'll never sell my gear.
Never. I feel like my life depends on it. Same goes for my dogs. They're a huge part of why I'm still here and haven't checked out. So I won't ever be without a dog for the rest of my life. They are that important to my well-being. Just like my guitars.
Wow....Thanks for sharing this with us, JC. Congratulations on regaining control of your life and focusing on the best things in life: like good music and dogs ;)
I could watch these videos all day long sir. Thank you!
Glad to hear that, S.
Your attention to detail is second to none! Digging through all the different versions of the schematics to find improvements is something most repair techs (in any field) just don't do. Outstanding work!
Thanks so much, Aaron :)
Hello Uncle Doug & Family, Kitties too, It pretty much goes without saying, that, you are the tube amp master. Beautiful repair and sounding oh so good. Olie and Jack have been practicing! The song 'One' by U2 is really easy and a good song. Good gravy, pulling a few G's in that little Rambler! Thank you, C.
So glad to see that you are the one to restore this beautiful amp. Only the best will do. Good job!
incredible find & great video. my introduction to the entire Bassman "thing" was thru a cheap clone called the MIG-50. i took it into a room, turned it up to 8, and was just floored. i'm a bassman guy ever since. incredible amps
When all is said and done! It’s great that you have an opportunity to play through these” legendary” amplifiers. Great work sir!
I agree, David. Thanks !!
Hi Uncle Doug. I want to tell you about a little trick that's almost always used when connecting a potentiometer like a rheostat, i.e., when you use only the wiper and one end of the pot, as you did when installing the bias-adjust pot. The trick is to directly short the unused end of the pot to the wiper with a short piece of wire. If you think about it for a bit, you'll realize that under normal operation, it doesn't change anything. However, in the case where the wiper loses contact, either momentarily or permanently, with the resistive strip, instead of the resistance going to infinity, it goes to the full value of the pot. Sometimes, this difference in behavior can save a circuit from damage, and sometimes it just makes the pot quieter if the pot is a bit dirty. This is just a little, zero-cost bit of sophistication in circuit design.
'61 was a mighty fine year.
Thanks for sharing your endeavours with us once again, Doug.
The pleasure was ours, Vinny.
That PCB inside looks gorgeous, the neat arrangement of all the caps is fantastic.. What a well designed beast. And what a fantastic re-build!!!
Wow, thanks so much, Demag :)
Um ótimo saturday para o Sr. Mestre thanks Sul do Brasil
"Drunken chimpanzees"? LOL! I spit out my tea when you said that. This resurrection was enlightening. I knew there were differences when Fender began using solid state rectification; but not to the extent you demonstrated. It now makes sense, tonally. Despite the improved input integrity. I did search my parts boxes for the requested items, but it proved fruitless. The switch to the normal channel toward the end of the audio test woke my ears completely. The tone was vintage sparkle, and reminded me of my old Bandmaster. A million thanks for sharing this renaissance of the Blonde Bass Man. Enjoy what's left of the weekend, dear uncle.
Thanks, Alex. You do the same :)
Thanks Again Uncle Doug. I learn so much from you. LOVE Jack !
I love working on these old point to point wired amps. There are very few things that make them unfixable. No matter how rough they may seem there is gold there.
I agree, OG.
Uncle Doug,
I would like to sincerely thank you for creating this fantastic channel. You are a fountain of knowledge, a generous and gifted teacher and a welcome respite for me during the past year.
You see, last may my lovely wife was diagnosed with a rare form of cancer and she is sadly in stage 4 with that cancer. I've had to quit my job as a zookeeper, which I loved, to take care of her and she goes through surgeries and chemo.I'm glad to do it, but it's hard in many ways.
I play guitar when I feel inspired, but about the only thing that I have enjoyed lately, has been learning how to repair and build tube amps.You. are responsible for the majority of that enjoyment, interest and the confidence that comes with the knowledge of knowing that I'm learning from the best. Sorry for the long and personal note. Thank you.
Thank you for this wonderful note, Greg, and for your very kind comments. If our efforts have provided you inspiration and distraction during this difficult period, we are sincerely glad.....and we wish you and your wife the very best for a speedy and complete recovery. Please keep us informed of her progress, and by all means, please continue to watch and enjoy our channel.
@@UncleDoug It's an honor to hear from you. Thank you so much for your words of support and kind wishes.. Our next step in her cancer treatment is to go to San Diego for another surgery and HIPEC chemo treatment. The cancer is so rare that there are no specialists in Northern California. When we return, and when I have some free tlme, I look forward to finishing my first full amp build, a 59 tweed style 4 x 10 Bassman. Then I'd like to go over/restore my old Marshall JMP. Until then, I will have a week or two while we're in the hospital to binge watch the remainder of your fine videos. Best regards and keep up the great work.
@@gregmenacho7667 Thanks for the update, Greg. I and our entire YT family send our best wishes to you and your wife for a speedy and complete recovery. Hopefully you will both be home soon, and you can resume working on your Bassman project.
Electronics, Music and 'Rods.....Great combination. Nice work on the Bassman - I'm learning all the while (UK).
Thanks, Dave. Keep up the good work.
Well done sir. I think I'll install a head rest on my computer chair before I watch the Rambler cruise again. Thanks Doug, love it.
Thanks for joining us on the video and ride along, Bob.
I hope you are keeping yourself safe during these difficult times. Stuck at home myself revisiting some of your old work. Excellent stuff. Keep the videos coming. Kind regards.
Thanks, Jono. We will :)
Thanks for another hit of the good stuff to feed my addiction, I wish I had been to that garage sale!
I think a lot of us wish that, Jeff. Maybe it's better that we weren't all there at the same time ;)
My ears seems to be drawn to the Fender 6G circuits, with this one being my favorite. I've been watching and re-watching your vids and have learned a ton. Thanks so much for doing these. The content is invaluable, and I'm truly grateful for all you've done on this channel.
You're quite welcome, Rob. Thanks for the nice comments.
Just an awesome in depth look at a great restoration...thanks!!
You're welcome, RW.
You can understand why top guitarists seek out old Bassman amps. That is an awesome tone. Great work Doug and such a pleasure to watch.
Thank you kindly, Glen :)
Thank you, Uncle Doug, for a veritable encyclopedia of valuable information in this video.
You're welcome, Michael :)
And must add yes quality of the craftsmanship is very important myself as well since by the day as I call it my hobby is a mechanic working on old excavating machines and forklifts detail to detail down to wiring and those capacitors look fantastic....
Thanks so much, Charles :)
Dearest Uncle Doug, You are amazing. Thank You!
You're welcome, Scott ;)
My neck hurts from the whiplash in the Rambler! WOW.
What a coincidence.....mine too ;)
Thanks for the comments on tube heater wiring. I'll be building a home brew stereo amp- nothing special, just a little 10WPC with 6AQ5s since I had a pair of CVP1s. I knew to twist the wires, but kits that I had built over the years had me tucking them down by the chassis.
Good luck with your project, CH. Do the filament wires like I showed you......it's the best way.
Thanks. Good to know I’m not alone in amp geekery and quality workmanship
Uncle Doug, you are a national treasure, your teaching will inspire a new generation.
I would love it if your get Jack and Ollie to turn it up a bit and blow the lid of of the joint.
That Bassman amp is capable of some serious mischief.
Of course the neighbors will complain, and call the cops. That is the price of rock and roll.
Who needs distortion or overdrive pedals? That amp can make some serious decibel levels.
Let it rip.
Thanks so much, Michael. To be honest, the amp is routinely set right at the threshold of pain for us making the audio demo. The microphone and recording gear tend to moderate the volume down to a tolerable level. Even if we ran the amp at 10, the recorded volume would still be about the same.....and we would be deaf.
@@UncleDoug I understand, in my opinion there is nothing sweeter than the pure tone of a well amplified instrument. I do enjoy the sound of a guitar.
But the amplifier has the power and the ability to add another dimension.
Not just roar and rumble, but a real singing feedback that can be manipulated by the player. That is what distinguishes one amp from another.
A Fender has a signature tone, that is different from and Ampeg or a Gibson or a Valco. If you wish to get pure clean tone, then the solid state amps are the way to go. With vacuum tubes there is a transfer of electrons across a distance that can not be duplicated in any other way than in a bottle. And that is why we love them.
@@michaelmenkevich5712 Very well said, Michael. Thank you for your input.
@@UncleDoug Thank you for the kind reply, you are a gentleman and a scholar.
I was thinking about your hot rod cars. Back in the day the drag races were big, but outlawed. In Philly we had the meadows and Decatur road, which were back roads with good asphalt and a sweet 1/2 mile strip. Every weekend the racers would assemble to try their latest jazzed up hotrod. Some great races.
Also some wild crashes. The cops would bust it up every so often.
Your interest in hot rods and tube amps is interesting.
And my point about pushing the tube amps is similar to hotrods.
You do not build a street rod to cruise along at 55mph.
And if you have a guitar and an amp, you crank it up and see what it can do.
Turn the amp up to ten and control it with the guitar.
@@michaelmenkevich5712 Thanks for your input, Michael.
So glad to see a lovely blonde Bassman come back from the dead!!! Always enjoy your videos Uncle Doug. A while back you answered some questions I had about stripping paint off of my 62 Bassman head. Your advice was very useful and much appreciated. The amp looks and sounds great and am so glad your were able to help another Bassman get back to their former glory! All the best.
Thanks so much, Stephen. I'm glad the advice was helpful.
Another great resurrection, you treat these old gems with appropriate reverence. Much respect for your work and entertaining dialogue.
Thanks so much, Keith :)
Im 78 years young and been a musician all my life and We used to in the old days call that little silver box mounted on the chasis of all the fender amps in those days the suicide box because if you were into repairing your own equipment as most of us were then you learned really fast to put the cover back on that thing when you were done diagnosing and repairing in there because if you were to accidently touch something in there you immediately realized how much voltage was going thru it
Yes, indeed, Douglas. The metal cover definitely serves a valuable purpose.
"It's a reflection of the care you took, while working on the amp circuit".. thanks for doing it this way!
a few years back, i've seen a documentary about the Aston Martin one-77 and they have highest quality standards even at spots that you would never see (most likely not even a mechanic), but they claimed that only this reflects the overall quality and craftsmanship that the buyers deserve.. i think you have the same understanding of what's "quality work"
I hope so, CD. I think that the process is every bit as important as the result.
@@UncleDoug i wish everybody was like this! Then we'd still have electronics that last 50 years or more, and are still repairable, unlike a lot of devices today that are built to last until the warranty is over to ensure recurring revenue for the manufacturer..
@@cdh79 Thanks, CD. Agreed :)
You sir are the Bob Ross of electronics. Absolutely brilliant.
High praise indeed, AS. Thanks !!!
Thankyou uncle Doug for the effort and time you put into your videos unlike others you don't compress one hour content into 10 minutes 🤘
You're welcome, Robert :)
Thanks uncle Doug I was having old school Fender circuit withdrawals, I just started watching the vid time to get back.
I hope you enjoy it, Eric.
I just picked up a silver face '70s bassman 50 ,beautiful condition ,it sounds fantastic with a bass and somebody properly added a master volume, it's one of the best bassmans that I've ever played through and I've had quite a few and I play bass through these things, very inspirational video 🙏🏼🎵🎵
Thanks, Charles. Glad you liked the video.
Another gem saved from the junk pile by the Master, Uncle Doug. I just love how you explain technical jargon and best practices so well...you never insult your audience and take a natural assumption we don't know. Example, how to properly wire the AC to the heaters with such twist and care to "drop them down," while elaborating that the DC wires laying around the chassis aren't as susceptible. I wish I had an electronics course instructor as patient and well-vocalized as you. Please keep the videos coming, we all appreciate them.
Thanks so much for your very nice comments, HP. It's great to hear that you enjoy our videos. We will ;)
Man, I need to take a course in amp building, your videos are SO damn cool uncle D. I'm jealous of your knowledge and skill. You also prevent people from making mistakes that will prevent hours of extra work. Again, much respect.
Thanks so much, PJ. Keep studying the videos and eventually you will be ready to start building your own amp. Best of luck.
Thank you for another wonderful video and you are such a good teacher. The Desoto Fire Flite is coming along nicely. It's going in for a custom "sewer pipe exhaust" next week.
Another gem from Uncle Doug!
Leo Fender knew that there are us bass players and then there are normal musicians.
"Normal" is in quotes, H. Thanks !!!
Back from the dead! Great job and sounds Perfect!
Thanks, MK :)
Another educational and informative video on a great find..Luck guy..! My head is exploding with all the lessons..Ed..U.K..😊
Glad you enjoyed the video, Ed.
What a Swiss Army Tone Knife Monster of a Beast! Me and my buddy Sam Adams will ride the storm out. You out did yourself on this one. Primo. Sometimes I get sobered up and tuned up mixed up... And our buddy David is a good egg ;)
It really does respond more to its tone controls than most amps I have seen. Very versatile !!
@@UncleDoug Amen.
wonderfully done. thanks for this story!
Thanx for your wonderful videos Uncle Doug.
You've worked on some sweet amps, but this must be close to the top of the pile. Thanks for another excellent vid,
You've done a valuable service to all aficionados by documenting original builds for reference. This isn't going to collect dust unused in a museum, it needs to work reliably. I bet Leo would do no less.
That's a good point, Ken. You can't have great tone and reliability with old, worn out components. I hope Leo would approve :)
I really enjoy watching old electronics repaired correctly. I'm worried that there aren't enough young people replacing the older guys. There are so many fields this is happening in. Guess that's just the way it is.
I'm pleased to report that quite a few viewers are both young and interested in tube circuitry, Michael. Who knows, maybe this won't be a lost art after all :)
I did a similar rebuild on a 59 tweed bassman '5f6-A, except I left it fixed bias. Got a beautiful cabinet from Rodgers Amplifiers before he retired. Great sounding amp. Say hey to Jack for me.
It's still fixed bias, Atop, it's just adjustable ;) Thanks !!!
Dear Uncle Doug, Just another fine job on this vintage amplifier, sounds so good through my headphones, what a great job... You are one of a kind, keep these videos coming.... sounds so good, I could listen for hours...
Thanks so much, Mark :) Will do.
Looks and sounds GLORIOUS! ...and I second what T Rob said below. Thanks for sharing this rare build.
Thanks, IPH :)
Nice demo chord progressions Uncle Doug! Very tasty! And the owner is one lucky musician. Please stay safe. You are a treasure.
Thanks so much, G :)
Nice to see Jack is still around!
That's what he said, Andy :)
Hi Uncle, I haven't been watching your vids the past 3 weeks, but I just passed by to say that by all means stay healthy, and that I wish you and your family patience and good luck during this hard times. I'll be back soon, cheers.
Thanks for your kind words, HV. Hurry back :)
