This video helped me solve a problem I’ve had for months on my hand made Champ in 5 minutes. Was about to replace all the tubes when I realized all I had was a bad connection with the pre amp tube in it’s socket. Bit of deoxit and we’re back in business after 4 months of sitting! Thanks for the help!
My 1431 is my baby. Got it in 2015 from an uncle and it sent me on a rabbit trail for a few years to track down the 1432 and 1433. My favorite amp series of all time.
Very nice and clean repair. I am 60 with only high school band experience but appreciate your old soul for mellow sounds and keeping up the old school equip ment.
The boots, girl, the boots!!! They look so good. The inside of this amp looked so pristine. Love your videos. You Pros make everything look so easy but it's not
Another great video! Worked as an auto tech in dealerships and the instructors always preached “KISS” keep it simple stupid! You can easily go KRAZY making a problem more complicated than it actually is. The hallmark of a great tech is keeping the diagnostics realistic and in an orderly fashion. Love the boots and the pupper needs a raise!
Ayo Coleen, I love your laidback style, no pressure, just relaxed poking around stuff and being curious. really something, makes me want to find my old soldering iron and dig in some guitar electronics.
Great video Colleen! Watching your videos is beginning to rub off on me. I had a strong suspicion you were gonna replace that cathode by-pass Capacitor! I thank you immensely for the knowledge you are sharing through your channel! God bless, Bob
Respect! Great find of the root cause failure. A+ for troubleshooting skills: 1) Duplicate, 2) Isolate, 3) Repair, 4) Verify. Best of luck with your successful business! Cheers from Spokane, Wa, d.
Great job troubleshooting, nice fix! The amp really sounded great when you were done. Several lifetimes ago I was a Electronic Tech, your video brings back memories.
My first guitar amp was a Silvertone 1482, which the neighbors always complained about. My next amp was a 100 watt Marshall Stack. The neighbor's learned very quickly how NOT LOUD the old little Silvertone was! BTW, Very cool! The Electric Lady.
Nice one, I have a 1472 setting behind me, my Dad found it years ago, love it, don't even need a distortion pedal, just natural tube & speaker distortion. Nice video.
Another interesting informative video. Old practice amps have a certain cool about them. Not that I'd trade anything I have for one now, but they are so representative of the time. However this Silvertone really does have an unexpected great wonderful tone which was a surprise given the bare bones simplicity of it. Sometimes less is more.
Thanks you for what you are doing. I love learning and seeing these old circuits. Great looking boots! Yahoo! 🙏-I came via your interview on TAVA with Skip.
Dang that was a really cool vid. I found your channel while looking for how to safely discharge amp capacitors. I think your other videos are good too, so keep it up!
At 4:10, you *do not* have to replace the entire preamp tube socket ---- you can just remove a contact from another similar mini 7 or 9 pin socket in your parts stash and swap it into the socket in the amplifier to replace that one defective contact! I guarantee you it will be much easier than drilling out the rivets and replacing the entire socket. The contacts are typically held in place by either a dimple in the metal terminal (underneath the socket), a punched out triangular flap ( a hanging chad?🤔), or just a bend or twist in the terminal. Typically pretty easy to remove after a squeeze with needle nose pliers.
@@Bunn4Funn, broken pins like that are pretty uncommon; I've been working on electronics for nearly 50 years and I've seen just a a handful of such failures. If the socket pins were green and crusty from corrosion, sure, it'd warrant replacing, but considering this amp is probably not used for live gigs, only for recording or basement jamming, replacing just the one defective contact seems justified. PS, I've worked on a fair number of Silvertones and Danelectros, the sockets aren't generally known to be problematic. Planty of modern Asian-made replacement tube sockets are way less good than the originals.
Suggestion: most times you can remove/replace just the bad tube pin connector (use an old socket for the piece). Save you the time of replacing the whole socket. Great job on the repair.
It's always fun to carefully touch a tube while in the back of your mind knowing there are hundreds of volts in there, then hearing a loud bang/crackle. 2:46
These are really cool amps to, this amp totally goes with Red Cowbow Boots. Oh nice trouble shoot, dug it keep doing these instructional videos totally great thanks
A solderless joint on that B9G socket ... I've never ever come across this .. it's amazing it ran ok from the get go ! I've never seen variable silver mica compression capacitors in an audio amp before ... they must be in a very high impedance circuit ...I don't usually spray clean pots that are this old ... I find they become noisy later ... you can't beat changing them for new ...
Gentle suggestion: J-hook the leads to preamp tube socket for mechanical strength instead of the solder securing the wires to socket eyelets as solder can crystallize and break free with time, heat and mechanical vibration in these ‘Hi Power’ jobs! LOL
You are very to the point of what is going on and why it is going on! Great video! I learned a little bit from this, you don't waste time over-complicating things! Any videos on a scratchy pot issue on a Marshall? I have a 50 watt with a Lar Mar master volume that is scratchy. They are sealed so I can't clean them, maybe a voltage bleed issue idk. Anyway great video, subbed!
Здравствуйте,спасибо за ваше видио.Сейчас очень мало в интернете есть подобные темы,если можно то выложите схемы тех усилителей которые вы ремонтируете .Анатолий,Россия.Москва
Never saw so many old amps in such a pristine condition.....as i have seen old amps in bad condition collecting dust in storeroom..... Tube amps are cool they have kind deep n clear amplification....... New all amps come with mosfets ic n transistors...... Old amps a bit had to figure out as no PCBs everything i bundled like birds nest ..... But clean amp just like this is eazy fix
Hi there. Great stuff you are doing. For a change of pace, can you fix a hybrid amp, the ones with the PCB with the tube sockets attached to it (like I have). I haven't seen a video yet on how to fix one. Other than fixing dry solder joints, I don't know what's what in there. Thanks.
What an awesome video ! I’ve always wished that I knew more about tube amps - I’ve only dabbled with solid state audio amps a bit. A friend of mine had an amp like this when we were kids, but his was always giving us BAD shocks if we played outside on his patio. I suppose it was the dreaded 2 prong AC cord ?
The variac that you have behind you caught my attention. I know what a variac is and some of its applications, but I was intrigued to know what use you could give it, so I thought about asking you, but before I decided to investigate a little and I learned the following: the variac serves to provide to an old amplifier such as those with vacuum tubes with the exact voltage with which they were designed to work, since in these this value is critical to obtain the correct sound in addition to not damaging them. Am I correct my friend?
Among other things, a variac can be used to slowly ramp up the voltage when powering up an amp that has not been powered up for years, thereby keeping it from potentially blowing up.
If i remeber correctely, these Sangamo capacitors are prone to failiure. Do you change them preventively or leave them in there and replace them only if something goes wrong ?
Sounded a lot better than the other demos of these amps I've heard. Could the filter and cathode caps really be whats making the difference? It seems too much of a difference to chalk up to the recording quality. The other demos weren't THAT bad. They all had decent head room but the other's overdrive was much more splatty.
Why no filter cap discharge? Many viewers may see your vid and start poking around the guts of a tube amp and get a surprise ⚡️ Plus, maybe cover the method of turning a two prong AC lead to a grounded replacement and removal of the “death capacitor,” and why. Nice boots though 👍🏼
Fazio Electric do you know of a good source on youtube to help me understand wiring diagrams? It is definite blind spot for me and it would be beneficial in my line of work and hobbies to understand them better. Thanks for your time :)
Crazy how clean it was inside

Love the gritty sound of that amp at the end!
Two awesome cameos: the dog...and the boots! Haha. Another awesome vid! Thank you!
My 1431 is my baby. Got it in 2015 from an uncle and it sent me on a rabbit trail for a few years to track down the 1432 and 1433. My favorite amp series of all time.
Neat little amplifier. I love the minimalist construction of the chassis, built to a price but still very robust.
Very nice and clean repair. I am 60 with only high school band experience but appreciate your old soul for mellow sounds and keeping up the old school equip ment.
Such a snazzy looking little amp and great repair work! Well done!
So refreshing to see a woman in this field. Sausage fest be damned
The boots, girl, the boots!!! They look so good. The inside of this amp looked so pristine. Love your videos. You Pros make everything look so easy but it's not
I am shocked by how clean that is !
I thought she was going to say everything in there was new.
That's the first amp I owned. Bought it from a friend for 15 dollars. Sounded great when driven with an MXR Distortion Plus.

Awesome job Colleen. I bet every repair isnt that simple. Nice boots btw
uncle Doug's videos are the cat's meow and yours are the dog's bark ....theramational!

That bit you played at the end reminded me of early Who.
Thanks you for what you are doing. I love learning and seeing these old circuits. Great looking boots! Yahoo! 🙏-I came via your interview on TAVA with Skip.
love the clean sound. A good jazz amp.
love the silvertones. great little amps. another fine job!
You’re a darn good amp tech!

Why not just replace and know they are new and good? Prevent future failure from the other old pins.....

I had one of those when I was a kid. I discovered the magic of a dialed in tube amp and was trying to learn crossroads and blew that sucker up!!!!
the cooles thing besides the amp repair is your red boots !!! lovely . Saludos
Suggestion: most times you can remove/replace just the bad tube pin connector (use an old socket for the piece). Save you the time of replacing the whole socket.
Great job on the repair.
Great job, amp sounds wonderful. It has that classic CCR tone when you cranked it up at end, love it!
Love your videos. Looking forward to the Patreon page. Keep it up!

Pretty, smart and quite handy. I love your vids 😍
Such a good sound for that small a speaker.
Your dog is so cool.
Glad to see your subs skyrocketing, Colleen! Fully deserved.
Awesome video! I really enjoy watching your work. Happy to be an early subscriber. You will hit 100K and 1M in no time.
Great K’Boy boots, nice job on the amp.
Such an awesome design.
These are really cool amps to, this amp totally goes with Red Cowbow Boots.
Oh nice trouble shoot, dug it keep doing these instructional videos totally great thanks
Rocking the red boots!
Pretty dang 😆 dang ol’ clean original amplifier...
Great work 👍

Nothing beats DeOxit D5 for most connection issues. My main go-to Solvent down here in New Zealand
That amp is really clean!!
You really work fast.
Great old amp. Keep up the great videos.
Gentle suggestion: J-hook the leads to preamp tube socket for mechanical strength instead of the solder securing the wires to socket eyelets as solder can crystallize and break free with time, heat and mechanical vibration in these ‘Hi Power’ jobs! LOL
I was always taught to make a good mechanical connection before soldering.
That's a gorgeous amp
Excellent work and neat video. Those old amps are awesome.
Wow nice red boots at the end :) Thanks for you're video I'm learning a lot and you're job is really neet ! keep it up
1:50 my favourite flavour of Deoxit.. Up here in Canada it is $27.00 a can! That's like 20 bucks US$. 😳
Cool boots. 😎 awesome work! I could have used your help with my Deluxe, before I made a mistake and sold it.
You are very to the point of what is going on and why it is going on! Great video! I learned a little bit from this, you don't waste time over-complicating things!

That’s a great little amp!
I still own a Silvertone guitar. It was my dad's. I believe it's a Teisco one from the research I could find.
The amp is remarkably clean inside.
Love that puppers!
Love these shoes 👍

Sounds great.
This is great stuff!
Wow!, a trimmer capacitor in a guitar amp. Never seen it before. What is it for?
Nice boots.
I’m in love.
WE ALL ARE LOL
Great !
Fantastic

@@bjorn2run thanks for your kind reply my friend.
My kind! Amps, music 🎵🎶 etc. Etc!
Isn't it better to run the neutral wire direct to the power transformer and switch the hot?
Robert Gray, the short answer is,, yes.
I find that E6000 adhesive works better for fastening caps than silicone, have you ever tried it?
Home Depot and lots of other places stock it.
If i remeber correctely, these Sangamo capacitors are prone to failiure. Do you change them preventively or leave them in there and replace them only if something goes wrong ?
damn that sounds pretty fine!
Sounded a lot better than the other demos of these amps I've heard. Could the filter and cathode caps really be whats making the difference? It seems too much of a difference to chalk up to the recording quality. The other demos weren't THAT bad. They all had decent head room but the other's overdrive was much more splatty.
Which DeoXit spray do you use?
Great Vid cowgirl !
Great job! Just curious to know how much does it cost to do this kind of repair?
May I ask: why do you replace the 10+10mfd cap and 10mfd cap?
great vid!
What's your process to check the bias?
Why no filter cap discharge? Many viewers may see your vid and start poking around the guts of a tube amp and get a surprise ⚡️
Plus, maybe cover the method of turning a two prong AC lead to a grounded replacement and removal of the “death capacitor,” and why. Nice boots though 👍🏼
