Let's Scratch-Build the SUPRINCETON......Part One of a Series

In Part 1 of this video series, we will begin to construct, from scratch, an amplifier and provide a new speaker for an empty 1954 Supro Supreme amplifier cabinet, sent to us by a viewer. All steps of the process are explained and demonstrated, from repair of the cabinet, design of the amp circuit and chassis, selection of components to purchase, construction of a sheet metal brake to form the chassis, and machining of the chassis for all components. In addition, we will take a break and go for a ride in a 1932 Ford Roadster.

We all Love you Uncle Doug. You are a shining ray of sanity in an often gloomy world.

[@UncleDoug]

That's nice to hear, CR. Things have definitely gotten a lot gloomier just recently.

[@Bob-Whiting]

Wait!, our Uncle is SANE?! Awwww, that's no fun!

[@michel333100]

Hi Doug, I have watched your channel for years. There's no one on the planet that could hold a candle to your skill of building amps and drawing schematics and explaining everything and your outrageous talent of building hot rod cars like the plastic models I used to build and paint as a kid by Mattel. There's no one on KZbin that is as entertaining as you are. I find you to be a diamond in the rough. You just don't find older guys in my age bracket quite like you. I think the world is lucky to have someone like you doing these videos and hope you go on doing the things that you do forever. Brings me back to a time when I was a kid and loved guitars amps and hot rod cars and surf music, but like my sister once said to me, you can never go back home .You have a way of mesmerizing people with the way you speak and your vast knowledge of everything. People have no idea of your genius. All I can finish with, is saying thanks for the years of videos. Michel Newell from Niagara Falls, Ontario Canada

[@UncleDoug]

Wow.....Thanks so much for the very kind and wonderful comments, Michel. Viewers like you make our work quite rewarding :)

[@jaypaulson5181]

I so appreciate the “take the training wheels off” direction- I fully believe that you need the schematic to understand the circuit, and make component choices from there. Building and troubleshooting are so much easier when you know what you are (supposed to be) looking at… Thanks Uncle Doug!

[@UncleDoug]

Glad to hear it, Jay. As a child, I begged for my parents to leave the training wheels on my bike.....but after a few minor crashes, I appreciated their "tough love" ;)

[@alexdeleon7135]

A scratch built vintage amp episode is a brilliant idea! It breaks the tried-and-true repair aspect of your channel into a new facet to this diamond called Uncle Doug. I am looking forward to the promised sequel to this exciting endeavor. Well done.

[@UncleDoug]

Glad you enjoyed it, Alex. All credit goes to the viewer who talked me into it :)

[@rocket400what]

Jeezus uncle doug, that home made press break is why we love your work. Fabulous as always.

[@edwardebel1847]

Mr. Douglas...your dry sense of humor is cracking me up...much better than most standup comedians these days...and then I stay for the electronic education...what could be better?!?!?! :-). (Gotta build me one of those speaker-wire handles! Sweeeeeeet!)

[@UncleDoug]

Thanks, Edward. We sold the original speaker wire handle on Ebay for $950.......minus fees, we cleared $1.62.

[@geraldnees1330]

beautiful hotrod, I've been a car guy since the middle '60s and have been around and involved with 'rods all my life. it's great to find another person who enjoys amps, music and cars....I almost forgot he cats.

[@UncleDoug]

It sounds like we are kindred spirits, Gerald. Thanks for your input.

[@Rugbyman269]

As a 14 year old here in England back in the sixties , I looked in awe at these kind of hot rods ,back then there was only one car in our road , and four motorbikes , however , even then I can remember a Chevy Bel air coming down the hill towards me , it looked like something from another planet and the sound of a V8 was very special.

[@UncleDoug]

Automobiles are such a strong part of our culture, Graham. I've been a car nut for well over 60 years :)

[@ericrawson2909]

Agreed. I saw a Bel Air way back when I was about 18. Also a Camaro that won a rally. Fell in love with these big V8s. Had company cars so had to drive four or six cylinder cars most of my life. Now I have an F Pace SVR. Love that V8 burble on idle, and the power is awesome, but inside the car you don't get that classic V8 sound that I love so much.

[@UncleDoug]

England has a proud history of sporty, quality automobiles, but none of them seem to offer the "V8 sound" you enjoy, Eric. I guess you'll have to find it vicariously through American vintage autos :)@@ericrawson2909

[@mikemoyercell]

The car looks so ,uch better WITH the hood sides. It is beautiful either way though of course!

[@UncleDoug]

I agree, Mike. That's the way the car has been ever since the video was posted. Thanks !!

[@telecatsermaster]

Home made press brake….. nicely done old man…..

[@UncleDoug]

Thanks, TM :)

[@bajaskier]

Olson Electronics was a chain of stores similar to Radio Shack in the Midwest... Milwaukee in my case. They carried a much more complete parts line than RS, and also sold clones of Knightkits under the Olson name. They also kept young gun bands (like us) supplied in mic stands (Atlas clones), microphones (Turner clones), and as you discovered, musical instrument speakers which were better than Radio Shack offered, but more affordable than Jensen or CTI.

[@UncleDoug]

Thanks for the interesting info, B :)

[@DeadKoby]

I'm in the Cleveland area... Olson operated before my time, but I've had some of their products through the shop.

[@nomadicnerd818]

Another fantastic video, and a timely, dare I say "uncle-ish" encouragement. Well done nudging people to step outside their comfort zones and develop their own BOMs! ...and then you highlighted the lesson by expressing your own misgivings about using the brake for the first time on a machined piece of metal. Ultimately you put on your big boy pants, trusted the tool, and ended up with a success. That is the best sort of mentorship. Also, the lope of a big cam is a thing of beauty. .

[@UncleDoug]

Thanks for all the great comments, NN :)

[@DeadKoby]

There's something always so rewarding about starting with a pile of parts, making a "thing" and seeing it come to life. Doesn't matter if it's a car, an amp, or really anything that you've built with your hands and mind.

[@UncleDoug]

I agree completely, DK. You spend years developing skills and a project like this is a great way to exercise them :)

[@williambock1821]

That Supro badge is slick! Building an amp can definitely be expensive but when you see a modern hand wired 57 Custom Champ for $1200,it takes some of the sting out of the cost of a home built amp. I have a lot of great amps (and some not so great,lol)that I wouldn’t be able to afford if I just bought them from a store. Plus it’s a lot more satisfying to build them. Can’t wait till the next episode.This is gonna be a cool amp!

[@UncleDoug]

Thanks for your very nice comments, William :)

[@nevillegoddard4966]

@@williambock1821. Yeah, & when you're building it yourself you can spread out the shell shock to the wallet by buying the parts stage by stage, & perhaps hide the cost from the missus more easily. Like my hifi amp & speakers I've built, which cost me about $5.5k, but spread out over 2 years, we're more like a dull ache, than a severe sting!

[@UncleDoug]

Spread out the misery......makes sense to me :)@@nevillegoddard4966

Nice job on your "Pat. Pending" sheet metal brake. Interesting enough I went to school with Pat Pending and his brother Bill the founder of the Billy Beer company. That was at Chris P Bacon Elementary School in Arkansas. I wasn't aware he moved to West Texas. Seriously though.....well done video and great concept for a series.

That National Amp I have... 1952..same circuit with 3 - 47k inputs, 6j7, 6sc7 preamp. I had to rebuild most of it as it had been stored in a high humidity. Wish I could post a couple pictures. Nice work as usual!

AAAAAArgh! Can't. Wait. For. Next. Video!!!! Going to have to rewatch some just to quell the shakes..............

As for the side panels, on is less drag, off is more showy. Do you prefer a nice dinner dress or lingerie? Depends on the situation I guess.........

Another great video Uncle Doug. Aluminium soldering is quite easy. You just need the right type of flux. The flux I use came with a MAP gas torch, and worked fine with standard iron and solder . I have found this useful for soldering to aluminium tape for guitar cavity shielding.

Without the sides! Nice and informative video, as always. Your yellow car reminds me the late Jeff Beck's. He had a very similar car like that, but I don't know where in England he could enjoy it. Their roads are very narrow. I'm not sure but I think most of his cars were left sided wheel! He was a very american englishman! Stay healthy and God bless you!

[@UncleDoug]

Thanks so much, Marc. Will do. Likewise :)

[@nevillegoddard4966]

Gidday Uncle Doug! 62 & my oldtimers disease must be trying it on! Sorry mate; I'd completely forgotten I'd already seen this part of the series, AND that I'd commented & liked it, AND that you'd kindly replied! D'oh! Nevertheless, I must have been so impressed & really, blown away by that beautiful '32 Ford that I forgot to say anything about the 'suprinceton'. I guess, like the '32, I just love brand new & reworked stuff going into old 'externals', helping them live to please another generation! Great fun! And before I forget, give Mitzy & Jack a headscratch for me would ya! I love them both! Unfortunately, I don't think I can have any more kitty cats - the poor buggers keep dying early on me! Great idea using dowels to plug the 12" speaker bolt holes! Nearly flamin invisible! I like how you installed the new handle; I'm gunna get meself some o that gun blue stuff! It seems to magically age brand new steel. Does it chemically bond with the steel? - & does it prevent corrosion too? It would be nice to see a complete modified circuit of your Suprinceton once you've finalised it. A little tricky to combine the 2 circuits together in my stoopid brain, & you draw them so well. Please tell me what a 'reverse audio taper pot' is? Is it, kinda 'antilogarithic'? And how would the tremolo pot respond to say, a log pot instead, for example? Yeah, so we all know we can't solder to aluminium right? Well, wrong. You can! I just watched Mr. 'Hackaday' do it! The trick is to plate the aluminium with copper first! All you need is some copper sulphate, some ferric chloride & table salt! Not too difficult, & I watched him use his resin-cored solder to perfectly tin an aluminium can & solder a resistor & an led to it. As bright & as shiny a solder joint as you'd see if it had been a copper can! Just miraculous! Impressive & unexpected to see a pink copper patch so well bonded to aluminium! No flames required. Especially easy when you're building an aluminium chassis from scratch! Of course, your new Suprinceton chassis would be all done & dusted by now, but maybe you could think about that for your next ali chassis. It was exciting to see all the new bits layed out there for the amp - like unpacking an amp kit! I bet it was fun for you too! What's up with that bender you made? You're gonna have folks & blokes wanting you to build them one of those too! It's a bloody beauty! I chuckled at the cussin & ICU comment ya funny bugger! Lol! Have I got it wrong or did you score yourself a real nice chassis hole punch set from a yard sale a while back? Or maybe it was Brad? Nevermind, the 'toob' layout looks nice mate, except I probly would have put the jacks in front of the 12AX7's to stop klutzes from damaging them & burning their unco little soft fingies. Tell me more about your legendary 'D' shaped drill bit! Where would I find out more about that? You nearly had me thinking you'd completely forgotten about the output transformer, but no, of course you hadn't! It's gunna be interesting to see where the sub-chassis for it will go though. I suspect there's not much room left inside the box. Last time I commented on the '32 Ford I likened it a formula one open-wheeler! Then I was thinking how much fun it would have been if it had a stick shift instead. But of course, the F1 cars now are even 7 speed autos! AND they have auto brake flaps on their rear wings now as they approach the corners. So you've got yourself a virtual 1932 formula one racecar there mate! Yeehah!

[@UncleDoug]

Greetings, Neville. Wow.....lots of questions. Gun Blue oxidizes the surface of the steel, protecting it from further oxidation. A link to the final schematic is included in the video description. You'll have to do an internet search for Reverse Log pots to get a proper explanation. Thanks for the soldering-to-aluminum tip.....I'll check it out. I did get a hole-punch set a couple years ago. I'll keep your suggestion on output jack positioning in mind for future builds. Merry Christmas !!

I'm excited to follow this project. I'd suggest using a eyelet board. It's easier to position the components. A lot of viewers might benefit seeing one laid out and installed. Looking forward to part two.

Greetings, Ray. I'm a dedicated believer in point-to-point wiring using terminal strips.....it's just my style :)

[@rayvoorhies7180]

@UncleDoug I like point to point wiring too. I wasn't sure if you'd done a build with an eyelet board. But I understand it's better to stick with what you like.

[@UncleDoug]

I think eyelet boards are wonderful for mass production, where the boards can be pre-assembled in quantity, but for one-off builds, I consider them to be an unnecessary complication. @@rayvoorhies7180

Great stuff, Doug! I just made a zero-budget current-limiter by splicing one extension cord in series with another. Then you plug a regular desk lamp into the one in series. LOL! Works! (No way to switch out the bulb though, so you have to unplug and replug the D.U.T. But the switch on the lamp at least cuts the power. This is what the kids would call "ghetto".) Have a buddy who does house wiring who's been telling me "I have all that stuff" for 2+ years now. Finally got sick of waiting for him to help. On with the Korg Mono/Poly repair! (Already have a Variac and Isolation Transformer, this was the missing link!)

[@UncleDoug]

Glad to hear of the rather rustic addition to the diagnostic arsenal, AQ. I hope it serves you well :)

[@AdmiralQuality]

@@UncleDougIt did! I brought the Korg Mono/Poly up slowly and was satisfied there were no major faults. Had already replaced the busted pot with a temporary piece of junk from some computer speakers (you can see it dangling out of the hole), so I then put it straight on the mains and lo and behold... kzbin.info/www/bejne/rXiYdmysmN-ieM0 Frankly I was a bit disappointed it was such a simple repair. But I'll take it! Taking an ain't-broke-don't-fix-it approach on everything else, including the filter caps. It all seems fine and zero hum. Amazing after 35 years in the bottom of my old music buddy's mom's closet. (That's what dented the front panel and busted the pot.) I intend to put it up on the market so "mostly unmolested" will be a selling point.

I bet in a prior life you were a master builder for the Egyptian Pyramids! What a talent you have among many!

[@UncleDoug]

Wow....Thanks so much, Gerald.

Aluminum is soft enough that you can safely use a wood cutting blade to cut it. I’ve been doing it for years without any problems. Another option for removing the handle pins is to center punch a dimple then drill down through the double heads that trap the bracket and push it down out of the cabinet.

[@UncleDoug]

Both are good suggestions, Tom. Thanks :)

I agree about the hood sides on, but can see that there are times where it can be fun to run without.

[@UncleDoug]

Thanks, RR. Fortunately, it only takes a couple minutes to remove them :)

For me, my first build I used the diagram. As I was building the amp, I referred to the schematic to see what that section looked like. I have no formal education on reading either, but having both, gave me the ability to see what I was doing. Then I pulled out my RCA tube manual to see the sections of the tubes on the schematic. I agree that just using a diagram may produce an amp, but having a schematic to use is really what needs to happen. Also, looking at small sections at a time and making marks on the schematic as you get through that part will make it easier. Small sections and marking off what you have done helps immensely.

Thanks for sharing, Jon. Excellent suggestions.

New Subscriber here! Loved the Amp work! Also really loved the Ford! I have a friend in WA that creates vintage amps and I really enjoyed visiting his shop! I'm down in FL now so I haven't seen work like yours in awhile! I'm also a car nut having restored several big 1963 Buicks! Thank you!

[@UncleDoug]

Greetings, LB. By coincidence, I have a 1963 Buick 401 Wildcat engine in my 1929 Ford roadster. What a wonderful engine it is !!

[@lotsabirds]

@@UncleDoug you're not kidding! My last one was a 63 Wildcat! Light Mariner Blue, mettalic paint! Loved it! My favorite motor was in it! The 401, that they sometimes labeled a 425!

[@UncleDoug]

The torque is breathtaking......instantaneous acceleration at any RPM.@@lotsabirds

[@lotsabirds]

@@UncleDoug Yep! You tap the gas and it sucks you back into the seat! I wish I still had that Wildcat!
