  • 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.

    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 UA-cam 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

    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!

    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.

      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.

    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!

      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!

    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.

    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.

    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!

      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 !!

    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!

    Hi Uncle Doug - I really enjoyed Part One, and am looking forward to Part Two. I recently added bias-wiggle Tremolo to my scratch-built 5E3 and was underwhelmed with the intensity. After a few mods, I finally got to an acceptable intensity (but I may go back and change the power stage to fixed bias). I'm very interested to see how you add tremolo to a cathode-biased power stage. Thanks for sharing this project.

    • @UncleDoug
      @UncleDoug  8 місяців тому +1

      Faced with the difficulties you described, I caved in and changed the circuit to fixed bias. Since this is a video series, I did not want to end up with hours of experimentation and uncertain results. My inclination was to apply the trem output to the cathode of the second triode......but that is also where the NFB connects.

    I bought what is supposed to be a 1948 Valco amp (the cab looks the same as what you have there) with the amp bottom mounted and accessible from the rear. It has (2) 6V6 tubes with some metal pre amp tubes. The OT is on the speaker. I need to service the filter caps before I play with it much more.

    • @UncleDoug
      @UncleDoug  9 місяців тому

      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

    Good job on the chassis fabrication, and the building of the brake.
    As far as the hood sides on, or hood sides off, I would take the indecisive approach and leave one side on and the other side off. You will need to decide if, left side on, right side off, or the opposite. I can't figure out everything for you!
