You hit, in detail, the things I was unsure about. Thanks for taking time to post this, I really appreciate the info.
Smashing job on this amp. The best part about this is including a demo by the owner. No one does that. Brilliant! - Mike from Black Cat Amplification (Baltimore, MD)
Oh snap! Look at this! Uncle Doug would be glad to see someone from the younger generation taking up this lost art. I know I am! Keep up the great work!
I learned basic DC and AC electronics when i was around 11 years old then learned RF and digital electronics. This was my hobby as a child. So I highly respect what you are doing. It amazes me that someone your age today has this knowledge. It's a very rare set of skills and knowledge you have today.
I just discovered you. I know nothing, zilch, nada about amps. You are mesmerizing. Just watching you work. I'm 72 and before I head to Jimi's abode, I'm going to build an amp! Thank you!❤
Hello from Northern Cali!! After watching your “1/4” speaker jack replacement” and “Draining your filter caps” videos I decided to repair my 1978 Silverface Champ myself. I successfully replaced my fuse link, installed a new Jensen speaker, and retolexed the top and bottom of the cab with red sparkle vinyl. I had never heard the amp in the ten years since it was gifted to me! It sounds incredible! I’m sure it could stand to have those old worn caps and resistors replaced and I now have the confidence to attempt the job myself. Thank you for the comprehensive and encouraging videos! Keep up the excellent work, Colleen!!
You can learn just about anything on RUclips! Gotta love it. No better feeling in the world, the satisfaction you get from learning how to, then successfully fixing your own gear. 😎
Nicely done! I think your videos fill a niche that others don't. You show clearly things like the layout, wiring (well explained) actual soldering work, component function/purpose, and more. This is super valuable for those just learning about amp work and what's often lacking in other amp tech videos. Showing the bias calculation steps (Rob's calculator! ) also great! Thanks and looking forward to future posts as well.
This is a perfect description of what sets her apart from so many amp repair channels. As a musician that began to take a keen interest in the technology of my gear and wanted to be able to effect smaller repairs about a year ago, it can be very frustrating trying to get a grip on so many aspects, but your explanations are not specially tailored to impress the Go-Go Gadget Cap crowd. I appreciate that you're willing to share your expertise and knowledge. Hope you can do this for a long while!
One of the clearest explanations on the internet of anything technical, let alone amp-related. Keep up the good work! It's so satisfying to see someone know exactly what they're doing.
I really enjoy watching you restore these wonderful amps. You are an excellent Diagnostician and Technician. As a musician who's played for over 50 years, it's a pleasure watching you do your work. 😁 👍
Solid! Commenters are right on the biasing. I tend to replace champ filter caps with a 4 node 40-20-20-20 in case they want to use the other version power supply. 40 is technically too high for a 5Y3 but who really cares. The other main mod worth doing is converting the tube filament winding to parallel from series.. especially on speaker changes. Helps cut out the hum. Great video! Keep them coming!
@@electrofrying1685 well.. I do this as a hobby and I work on customers amps... What is your point ? She is great and I am so happy to see someone so young doing this... Dont try to make it more than I am saying.. thank you
I just stop by, to check out on the video and I was mesmerized by it. This young woman is really a pro on what she does. I become a subscriber in a heart beat. Thank you
So nice to watch you, a young woman who not only has knowledge of electronics and such but is even interested in this to begin with......so Awesome. I'm an old geezer who plays several instruments and this takes me back to a time around 73 - 74 when I would plug in my 67 Gibson SG Jr. into my 74 Fender Champ. You can imagine the sound that single plastic P- 90 pickup strapped in a plank of deep burgundy mahogany in my Champ cranked up to 10......oh HELL YEAH! I know you Guitar player's out there can tell this Deadly combination is nothing short of a ROCK MONSTER, lol.....anyways love this video.....🎸🎸🎸♥️
Ah, my first amp, and my favourite. Bought it 2nd hand in 1978, never forgot how good it sounds, as per your customer's demo! Thanks for the memories :)
Stumbled across your channel by accident and it was a lucky get. Retired electronic/tech/engineer with 38 years experience. Also a guitarist. I still have the first amp my dad bought me. 64 Fender Princeton that I will be restoring. Excellent videos. I was watching this video and just wanted to comment on the part installing the multi cap in the chassis. The choice of not grounding to the chassis. That chassis is s huge heat sink. Lol. We had an iron we called the solder bat for things like that. This is great. I subscribed. Thanks!!!!!
Great job, well done! Just two wee tips from my side: Those late 70s cheapy Fenders often have one massive construction failure, that Fender probably came up with to lower production costs: Instead of running twisted leads to the filaments of the tubes and balancing the center either via grounding a centertap of this winding or by adding two resistors (usually 2x 100 ohms @ the pilot lamp), the changed to running one side of the filaments via the chassis - which was a VERY bad idea... This should be modded back to twisted wires, which will result in a significant noise reduction! I did this mod with my 79 Musicmaster Bass amp - and it was a MASSIVE improvement! Also, I would solder the filtercap directly to the chassis, to prevent it from starting to rattle in the future. Check out Mr Carlsons soldering tips - he uses a modded soldering-gun for this purpose - works great! For biasing cathode biased amps, a "Resistor decade" (don't know, if this is the proper word - we call it Widerstandsdekade here in Germany) can be very handy - so you can dial in the resistor values, until you'll find the perfect bias, then replace the item with a proper resistor, and you're done! Greets from Salossi's Ampschmiede :)
I feel so old because I did this stuff so long ago but wtf, it's nice to see people still learning from it! I mean that in respect because it isn't as easy as people think.
I just wanted to say Thank you for sharing! It is so interesting how you diagnose and bring back to life vintage amps! When I watch you work, I understand more and more about electronics. You really inspire and encourage people! Thank You!!!
Thanks for the video. I'm going to make a cap voltage discharge tool so I can get inside of my Music Man 65 and tighten up some pots and take a look around. In an industry that's been so dominated by guys, it's hard not to sound patronizing when I say you are an inspiration.
Hi. Short version :Solder a 220k or 330k resistor in parallel across the first filter cap ( normally ) or across any filter cap from B+ to ground. Better if the resistor is 2 or 3 W . The heater elevation, also does the job. With a value of 220k , a 32uF cap and a voltage of 300 V on B+n you can achieve a safety threshold voltage of 10 volt in maybe 25 seconds. Always check the voltage with a tester before to put the hands in.
Your appreciation for respecting original designer and yes thanks for showing all steps involved. As time goes on you will become a true Luther of Amps and I'd assume you are dialed in to the movements of the axe role.
By sheer dumb luck, my first tube amp was the very early 1963 Fender Blackface Vibro Champ. I got that amp in the very early 80's for next to nothing and wish I had it today. I plugged my brand new Rickenbacker 360 WB 6 string into the Vibro Champ and that's when the lights went on about the tube tone! A big step up from solid state tone!
I have this exact amp. It's so addictive to play on. I'm always blown away how an old school bedroom amp has stood to amps far above it's price range, for decades. Love your channel. I've worked in low voltage for the last twenty years and really want to build my own amp. I've been building transformers and fly back coils for the last year, or. I need to get back to work. Channels like yours are inspiration. Thanks!
Very nice. I had a Champ at least the same age that I modded - blasphemy I know - but no electronic modifications. I put in a heavier 10" speaker. I did have to enlarge the baffle opening as well as carve out a bit more space for the flange of the speaker but I had tested it first and it was definitely the sound I wanted for clean jazz and a browner rock sound with a pedal. I still own an Ampeg Gemini VI (head put in its own cabinet) that is spectacular. It's got the tremolo, reverb pan and an accordion input! Someone should have cloned that amp. Enjoyed the repair and I'll check out others. Cheers!
Great job, amp sounds killer! My first amp when I was 13 was a 1965 Blackface Vibro Champ. There was no distortion pedals back then so I use to put it in the closet with a bunch of pillows and crank it up. Then the 'Maestro Fuzz Tone' came out and I could take the amp out of the closet and play it without driving my parents nuts.
Nice When you were installing the two jacks, I was thinking please don't use pliers.... and you didn't. Proper nut driver Professional. You are a special young Lady. You have my respect.
Thoroughly enjoyed this video and will now make my way through your other projects. What I particularly liked was the pace of delivery plus the on-screen notes about the function and impact of certain components (and the impact of changing the component value on the sound) on the circuit, and the way you highlight the section you’re speaking about on the schematic and layouts. I feel functionally dyslexic when it comes to understanding schematics etc, and this helps immensely. Thank you.
Hi found this by accident when could sleep tonight ... wow great stream and awesome job showing/telling changes you expect to do to restore back! Love it Good job young lady keep on preserving amps !
Excellent presentation style. Rushing around inside a chassis is a bad idea and I dig your relaxed, yet to the point attitude. Liked & subscribed - and a reminder I need to give my old '65 VC a service! (and nice to see no misogyny in the comments section too, long may that continue!)
I had my Champ stolen. It was a really good one from around 72. It was the best one I've heard outside of an old friend's Vibro Champ that turned out to be malfunctioning, in a spectacular way. When he got it "refurbished" it ruined the amp's magic. That was an exceedingly rare, freak occurrence, so everyone, don't hesitate to get your amps maintained.
Great job. I tried for the first time the other day to change the electrolytics on my 66 deluxe reverb cct board, and found it quite difficult, you make it look so easy. I manged to do the single, but couldnt get the doubles in. lol Will try again when i get the time and have calmed down. Thanks for the tutorials.
Not every day we see such a qualified and knowledgeable amp tech who happens to be a young lady. Outstanding, and great explanation as to each step, the "why" for changing out resisters to capture proper performance. You're the only tech I've heard mention 75% plate dissipation...most of your colleagues shoot for 70%. That's fine by me, you're quite talented.
70% is the target for fixed biased amps. For cathode biased amps such as the Champ, 100% idle plate dissipation is the target for the best tone and tube life.
You do nice work! The only thing I would change would be to make the cathode bypass capacitor a 50 volt part, since you now have 32 volts across it and it needs to be derated further because the 6V6GT is underneath, cooking it. For the electrolytic tabs, I have a beastly 450 watt weller gun! Nothing like a fire-breathing dragon for those tough jobs! 💪 You have tremendous expertise! Keep on truckin'!
i see that Beatles picture hanging on the wall...I was 13 when they came out..Wow you should have been there..Had to wait in long lines just to buy the 45 record i want to hold your hand/flip side i saw her standing there.....What an amazing time in my life..Dont think we will ever see anything like that again..
This is how you do an instructional video! Great camera shots and lighting; clear, concise descriptions of what you are doing and why; and I really like the supplemental notes added in screen. Subbed!
Absof###inglutely! I've been building guitars and basses for about 25 years, playing them and working on them since 1986. I replaced the stock pickups, with Dimarzio pickups, in my first guitar, a Japanese made Kramer Focus 4000, the day after I received it. I replaced the Dimarzio set with a set of Seymour Duncan pickups, which are still in that guitar. All these years later, I NEVER did anything to the inside of any of my amps, aside from replacing tubes, de-ox some pots. This was as good, or better, than ANY work done, and explained, on an amp that I have ever seen. Like you said, clear, concise, and as thorough as I would want it, because I understand everything she's doing, why she's doing it, why it makes sense, and I'm not getting overwhelmed by details and tangential information that isn't pertinent in the moment. Combine that with the relaxed tone of her delivery, good pacing, and easy to listen to voice, and I would feel confident, right now, that if you put that amp in front of me I could follow her video and do that job.
I love the short explanation text that gives us a quick idea of what some of the lingo means and what the components are doing in the circuit, etc. That's really cool. I service my own vintage amps and gear, but I don't actually know what most of the stuff does. I just replace filter caps, replace way out of tolerance carbon comp resistors, rebuild negative bias supply, and clean stuff up while I'm in there. Your vids are rad
I enjoyed your work once again. A Vibro Champ was my First amp back in 1971 blew it out at the first band practice when my friend showed up with a new 1971 Bandmaster , which was funny because a TV show "My Three Sons" had an episode where the same thing happened to one of the sons fender amp. I replaced it with a Vox Pacemaker and then a used Fender Super Reverb.
150 cable channels and nothing on so I watch amp rebuilds. And I love it! So glad I found Fabio Electric! You do such a great job! Dave Gries of Gries Amplifiers does an amazing job using the Blackface Champ as his base for building his Gries 5. It is my main gigging amp for low volume gigs. My favorite design along with the Deluxe Reverb.
Amps are best left stock; pedals can boost and add effects. I've got a Fender bassbreaker 007 ltd that has gain control, treble boost and two 12ax7s and a 6bq5 for 7 watts with a 10 inch greenback that has the crunch you demonstrated in the beginning of the video, keep on doing the great 👍😃 work 👏👌🔊🎸
100% correct. There are so many discussions on single ended bias out there. Most champs with the 470R bias resistor are dissipating well over 100% and have been going for years. If it's not redplating a lot of folks seem to like them that way. I'm with you though, cooling them down a bit is a good idea
True, although a little note about terminology. The reason because you can push the dissipation at 90-100% in this case is because the power valve is cathode biased. Not because it is single ended. - Cathode Bias: 90-100% Max Dissipation - Class A, Fixed Bias: ~90% Max Dissipation - Class AB, Fixed Bias: ~70% Max Dissipation These are just guide lines though. There is a really nice video of Uncle Doug in which he compare different bias level and the tone associated. GREAT VIDEO nonetheless! Great repair and servicing.
Colleen, lassie, we need ye in Scotland ! Glasgow to be precise. Seriously, these videos are a joy to watch and ye are a bonnie lass indeed. Looking forward to many more. 🍀🌹🍀
I never opend any of my amps ,never have any intrest what so ever whats in there. Then you pop up on RUclips and hocked me right up😀 You are so Good to explain ,and the camera is always perfect placed. All the best to you from Tommy in Sweden 👍

Not every day we see such a qualified and knowledgeable amp tech who happens to be a young lady. Outstanding, and great explanation as to each step, the "why" for changing out resisters to capture proper performance. You're the only tech I've heard mention 75% plate dissipation...most of your colleagues shoot for 70%. That's fine by me, you're quite talented.
70% is the target for fixed biased amps. For cathode biased amps such as the Champ, 100% idle plate dissipation is the target for the best tone and tube life.
You do nice work! The only thing I would change would be to make the cathode bypass capacitor a 50 volt part, since you now have 32 volts across it and it needs to be derated further because the 6V6GT is underneath, cooking it. For the electrolytic tabs, I have a beastly 450 watt weller gun! Nothing like a fire-breathing dragon for those tough jobs! 💪 You have tremendous expertise! Keep on truckin'!
Moving it farther away from the resistor would be a good thing also_
That guy Taylor was pretty good! Awesome work. Sounds much better.
Great work and nice playing from Taylor.
Cool to have the client demo t her final product- sounds great !!
i see that Beatles picture hanging on the wall...I was 13 when they came out..Wow you should have been there..Had to wait in long lines just to buy the 45 record i want to hold your hand/flip side i saw her standing there.....What an amazing time in my life..Dont think we will ever see anything like that again..
Watching her take the mods off was oddly satisfying! Looking for a champ now.
This is how you do an instructional video! Great camera shots and lighting; clear, concise descriptions of what you are doing and why; and I really like the supplemental notes added in screen.
Subbed!
Absof###inglutely! I've been building guitars and basses for about 25 years, playing them and working on them since 1986. I replaced the stock pickups, with Dimarzio pickups, in my first guitar, a Japanese made Kramer Focus 4000, the day after I received it. I replaced the Dimarzio set with a set of Seymour Duncan pickups, which are still in that guitar.
All these years later, I NEVER did anything to the inside of any of my amps, aside from replacing tubes, de-ox some pots. This was as good, or better, than ANY work done, and explained, on an amp that I have ever seen. Like you said, clear, concise, and as thorough as I would want it, because I understand everything she's doing, why she's doing it, why it makes sense, and I'm not getting overwhelmed by details and tangential information that isn't pertinent in the moment. Combine that with the relaxed tone of her delivery, good pacing, and easy to listen to voice, and I would feel confident, right now, that if you put that amp in front of me I could follow her video and do that job.
I suck at soldering lol
The mods might have been gritty, but this is a greatly improved tone. USEFUL in the studio!
Colleen, Another great video with everything explained in detail you're the best in my humble opinion
Ed
Hey! Great job, very thorough. I did notice that the Warehouse is an 8ohm speaker, but the Champ calls for a 4ohm (I think!)
Eagle eyes Lee Parry.
They make the warehouse speakers in 4 ohm. I have one in my 5f1 copy I built last year.
I love the short explanation text that gives us a quick idea of what some of the lingo means and what the components are doing in the circuit, etc. That's really cool. I service my own vintage amps and gear, but I don't actually know what most of the stuff does. I just replace filter caps, replace way out of tolerance carbon comp resistors, rebuild negative bias supply, and clean stuff up while I'm in there. Your vids are rad
Got to love the creak of those old eyelet boards.
Great amp restoration and love the clear explanations of the things you were doing! The resulting amp sounds fantastic!!!
HINT - Use your multi meter set to Current or an Analog Ammeter in your ground jumper to measure Bias current directly. Great Job, you do Good Work.
Good job letting unintentional asmr showcase your style. Subbed....
You and uncle Doug should team up. That would be fantastic.
Uuhhh...? No!
These amps are SO GOOD cranked. A great example of a well-kept Champ was demoed by Ariel Posen for someone like Collings
I really appreciate the education about guitar amps. Thanks for making these vids.
Good job ! In Single Ended, 100% for plate dissipation is good, no problem. 75% is for PP.
ahh, the franken champ. humans gotta human. nice job on the rollback and good video detail (with actual lighting!!)
I enjoyed your work once again. A Vibro Champ was my First amp back in 1971 blew it out at the first band practice when my friend showed up with a new 1971 Bandmaster , which was funny because a TV show "My Three Sons" had an episode where the same thing happened to one of the sons fender amp. I replaced it with a Vox Pacemaker and then a used Fender Super Reverb.
Finally someone who understands electronics.
Just an amazing video. So peaceful with educational content.
150 cable channels and nothing on so I watch amp rebuilds. And I love it! So glad I found Fabio Electric! You do such a great job!
Dave Gries of Gries Amplifiers does an amazing job using the Blackface Champ as his base for building his Gries 5.
It is my main gigging amp for low volume gigs. My favorite design along with the Deluxe Reverb.
I use the same calculator. It sure makes life easier. Thanks for the great videos.
Thanks for sharing! Long live Fender ☝🏻
The joy and comfort when a shirt fits just right
Wow!!! What a huge difference!!!
Amps are best left stock; pedals can boost and add effects. I've got a Fender bassbreaker 007 ltd that has gain control, treble boost and two 12ax7s and a 6bq5 for 7 watts with a 10 inch greenback that has the crunch you demonstrated in the beginning of the video, keep on doing the great 👍😃 work 👏👌🔊🎸
Nice job, lady! And the customer looks stoked...win-win!
Good video! The 70% dissipation rule doesn't normally apply to single-ended amps, so for a single 6V6 you can bias more around 90% at idle.
ah that's great to know! Thank you :)
100% correct. There are so many discussions on single ended bias out there. Most champs with the 470R bias resistor are dissipating well over 100% and have been going for years. If it's not redplating a lot of folks seem to like them that way. I'm with you though, cooling them down a bit is a good idea
True, although a little note about terminology. The reason because you can push the dissipation at 90-100% in this case is because the power valve is cathode biased. Not because it is single ended.
- Cathode Bias: 90-100% Max Dissipation
- Class A, Fixed Bias: ~90% Max Dissipation
- Class AB, Fixed Bias: ~70% Max Dissipation
These are just guide lines though. There is a really nice video of Uncle Doug in which he compare different bias level and the tone associated.
GREAT VIDEO nonetheless! Great repair and servicing.
Colleen, lassie, we need ye in Scotland ! Glasgow to be precise. Seriously, these videos are a joy to watch and ye are a bonnie lass indeed. Looking forward to many more.
🍀🌹🍀
I never opend any of my amps ,never have any intrest what so ever whats in there. Then you pop up on RUclips and hocked me right up😀 You are so Good to explain ,and the camera is always perfect placed.
All the best to you from Tommy in Sweden 👍
Sound is a lot better after it's return to near standard specifications, the speaker suits the Guitar players style very well. Learning a lot from watching you work, thanks.
