The Nightmare on YouTube Street: Repairing a 1950's Stewart Amp

In this unusual video, I feature both the restoration of an early Stewart brand amplifier and the trials & tribulations of amp repair in general. Despite all my best efforts, I cannot make the original circuit sound good.....so I have to resort to extraordinary measures. Hopefully, the audio test at the end will verify the success of my efforts. Our second feature will be Part 2 of the 3 x 2 Carb Modification to the 1930 Ford Coupe and will include a felonious test drive guaranteed to warm the cockles of your heart.....whatever the heck that means :)
NOTES: 1.) I did not replace the blown speakers because the owner of the amp already has a nice pair of replacement speakers which he will install once the amp is returned. 2.) For those concerned about the placement of the vacuum advance line, please read the following: www.chevellest...

Hey, I graduated from R.E.T.S. in August of 1962, here in Philadelphia, Pa. RCA hired me the same day I graduated and placed me in the the apprentice program. When I was drafted RCA held my job until I returned from Nam. During my Army service I worked in High Frequency Radio Repair and middle guidance systems for artillery. At RCA I rose up the ladder quickly, from TV / Radio field service to Chief shop tech. In 1968 I moved into teaching until 1974 where I took a position at the RCA research center in Princeton. I worked there at various levels until 1990. Then I took a corporate position in Washington, DC and New York City. I left RCA in a massive downsizing action and was out of work for the first time in 32 years. RCA gave me a year of severance. Going back to school for computing was my next move. The last ten years of my work life I taught college level physics and electronics. In my retirement years I restore vintage electronics equipment and home items like Radio, Tv, computers and test equipment. My technical school education took me a long way in life.

One hour and 13 minutes of Uncle Dougy pure goodness, woot! I'm glad you made the decision to put a transformer in the amp, I was wincing all through the part where you were trying to get a solution without one (where really the only safe way to run it would be through an isolation transformer). That rat rod is a _Sweet Ride_ too and the triple carbs kicking in sound niiice. I'm not normally a safety freak when commenting but perhaps double-nutting that additional spring return would be a good idea? just in case the engine vibration backs it off of the all-thread while driving.

The power transformer you installed might have been enough for 2 6V6s in parallel for 10+ watts. The owner should install a pair of 4 ohm speakers to make the whole amp a winner! You did exactly what you should have done! To spend the money on a vintage amp, to go gigging with is the absolute smartest way to go. Safe, sounds great, a win-win! You did not have to restore the series filament circuit and get shocked, all you have to do is get in the '30 Ford Hotrod and engage the 3 carbs to give you the Fiz! Love Ya Uncle Doug, you are #1!

Incredible talent, Uncle Doug, from machining engine and body parts to repairing and explaining electrical circuits in guitar amplifiers. And, if that wasn’t overwhelming enough, you can play guitar as well. I have learned such a great deal from your clear instruction about amplifier circuits and how and why their different components work together to create amplification. You are an incredibly detailed and patient teacher. I have a Kalamazoo model 2 amp that I have recapped twice over the past 47 years, and I’m planning to recap again, get the tremolo working, a try to quiet the persistent hum. Do you give guitar lessons? I play a little but clearly you know some great licks! I continue to look forward to watching your library of fascinating videos. Thank you for your instructional and entertaining videos! -Dan W

Great job on the 3X2's Doug. Based on my unfortunate experience with a fuel line popping off and causing a minor "overheating" of my car, I respectfully recommend hose clamps on those fuel lines.

@pneumatic00 4 года назад

Thanks, Doc. The fuel pressure is limited to 3 PSI, but you make a good point. I will add the clamps......but only if they are certified to be cancer free.

Like yourself I am into hot rods, retrorods and custom work, I have under taken custom painting work and Airbrush work in the past as I have airbrushed for many years. I have just recently purchased the innards (circuit) to a original FuzzFace fuzz pedal and put the circuit into a more pedalboard friendly enclosure that I customized with metalflake and candy paint for fun.

I sold my Strat and Fender Gear, Ordered a Knockoff Jazzmaster and bought a Hammond Organ Amp modified for Guitar and an 8 Inch Celeation speaker but no cabinet. Now i want to upgrade the cheap Jazzmaster and rework this Boutique amp for reverb and anything else we can build in Tubes. Then in this video the 34!!!!! With Tripower and progressive linkage. I was so impressed. I can do cars anymore but i did have tripower once and made the linkage so poorly the spring to overcome the end carbs was too strong. Once you got to the hard part about 3,000 to go further it took so much pressure you just floor board the gas to 6.500 and the car would rip your head off, it was so crazy.

This is one of the best videos on you tube I feel, because it is a nightmare of an amp, it shows us the best examples of bad engineering and safety issues. Thankyou Uncle Doug your the best!

Wow Doug, that horrible snowy landscape in your backyard reminds me of the sad song "The Blizzard" by Jim Reeves, the man with the wonderful velvet voice, who passed away well before his time.

@UncleDoug 4 года назад

Jim was lucky, Berre. By dying young he avoided the nightmare I faced trudging through 2" snowdrifts to get some Ovaltine at the local 7-11 ;)

Man, was that ever sweet! The amp and the old A. I am a recent sub of yours, more into Hi Fi amps as I cant play a lick. I am into old rock, Willys jeeps, hot rods, and tube gear of any kind, and admire anyone who can play guitar! Oh and I also have the shop cats who are just as helpful as yours. Thank you Uncle D. Cheers from the Pac Northwest!

Hi uncle Doug. Great redo of the Stewart amp. The 50c5/50xx widomaker amp series, I never plan to fix , but repurpose into a safe , good sounding amp as well. Your expertise , speaker and cabinet make that amp shine. Great job on the vintage vehicle too!

Great job Uncle Doug, that’s a lot of work that you put in. A total redesign and build to get an amplifier that is safe to use and provides a great sound, that was a total nightmare of an amplifier. In hindsight you should have just returned it.

@barbsfpv3066 2 года назад

This was a great resurrection video. However, you replaced a push-pull amplifier with a single-ended one, and harp players absolutely 'love' their push-pull amplifiers because of the harmonics and saturation. So you made an amp that works, and sounds great, but I think as a harp player they were probably hoping to get back a working 50L6 push-pull amplifier circuit. That's what I was hoping to see too, a reworked schematic with push-pull 50L6's, which would have screamed, and sagged, and sounded great. I had an old Pacemaker PM-33 that had push-pull 6L6 output and the tone was insane. I absolutely loved it, but then it died in a wildfire (one of the tragedies of living in California). This isn't criticism or anything, just disappointment. I love your videos, they're always so informative. I'm learning a ton from them. Thanks!

@UncleDoug 2 года назад

I'm sorry for the disappointment, Barbs. Some might say that I took a non-functioning death trap and turned it into a great sounding amp. Single ended amps have wonderful harmonics and saturation. Bottom line, the owner was thrilled, so I guess it all turned out OK.

@raymondheath7668 4 года назад

This video helped me a lot! I too have a power transformer that had the wrong voltage for my output tubes. The resistor capacitor setup that you used brought my voltage down to +300 volts and the rest of the circuit nodes up to the input went perfect

I'm glad the video was helpful, Raymond.
