Part 3 of the Suprinceton Video Series: Final Wiring, Assembly & Testing
HTML-код
- Опубликовано: 7 дек 2023
- In this third and final video in the Suprinceton scratch-build series, we will complete the wiring, test the circuit, install the chassis in the cabinet, and do a final, detailed audio demonstration. Several careless oversights are remedied, but the final outcome is guaranteed to thrill and amaze all viewers :) In addition, we will take two musical drone voyages over interesting terrain and view a cavalcade of kitties.

My dad passed away last September and I have been meaning to write this for a while.My dad got great enjoyment watching and learning from you and at the age of 80 decided to built a Valve amp which worked !! better sound quality than all the digital stuff he had purchased over the years.Just want to say thank you for inspiring people to have a go.keep up your great work all the best from across the pond.
thanks again terry
Thanks for sharing this very nice story with us. It's great to hear that our videos are helpful and appreciated :)
Uncle’s Doug video series legacy will outlive all of us and inspire millions-mark my words
We hope you're right, Fuga. Thanks !!
It's beaming out into Galaxies Far Far Away.... 🇨🇦🤓✌️
I hope we get some interstellar royalties :)@@garymallard4699
There are no mistakes unless it’s in the final product! That’s just part of the creative process. Excellent work as always!
Thanks, Ben. You're right.....corrected mistakes during construction are simply part of the evolutionary process :)
I am reminded of Jackie Gleason's reaction to the sup of coffee he was brought at the top of his show - wooooow! (sp)
Thanks, Andrew. I remember it well ;)@@andrewgillis8572
Uncle Doug
You are a blessing and a Godsend
I am lucky to have come across your presentations as I attempt my first amplifier repairs/modifications
Please please keep it up
Thanks so much, Ed. We're here for you :)
I'm sure you will regret that because of all the stupid newbie questions I'm gonna be asking now...
My current project is a silvertone 1482
Thanks for the reply
I trust that you will attempt to answer all your own questions and do adequate research before relying upon outside help, Ed. Good luck with your project.@@edhelmstetter2741
@@UncleDoug Here's one for you is it normal for that 1482 single 12 to light up the current limiter lamp a little bit if so it makes it very hard to get correct voltage readings. If not then there's that problem...Conundrum for sure
As it is the amp works but no tremelo. Tremelo worked before I replaced caps and resistors. Finding the issue should keep me busy for a while
Thanks for the help
It depends on the wattage of the bulb, Ed. A 100W bulb would definitely illuminate, while a 250W might not. The brighter the glow, the greater the reduction of circuit voltage and current.@@edhelmstetter2741
Thanks again Uncle Doug. Another masterpiece.
Id like to give a tip for collecting and isolating drill chips. By placing a collapsible rubber cone or a wax cup which is flanged that can be taped, over the drill coming through. In addition , a piece of duct tape on drill exit side will capture most hot chips. Duct tape around the drill side with the sticky side creating a crinkly sleeve to drill into. Cheap wide masking tape is easier to use and cleans up quickly.
Thanks for all the useful tips, Bob.
Doug, your RUclips channel is now officially my favorite. You're the Bob Ross, Jaques Pepin and Bill Murray of amp geeks. This series, like all your videos, was utterly captivating, and the results sound fantastic. With this design is the overdrive we're hearing from the preamp or power tubes? In some future video, would you please consider discussing the difference between preamp and power tube overdrive and how to get them? If you've already covered this, would you please direct me to the video(s)? Thanks!
Thanks so much for your very kind words, Dave. The only overdrive I really noticed was with the low gain input and relatively high volume setting. Since the circuit has no Master Volume control the distortion is probably from the output tubes. I am not really an expert in distortion, since my audio demo's are generally fairly clean. There are all sorts of great sources on the subject on the Internet, however.
Wow, I'd be hard pushed to let that beautiful amp go, after putting so much heart and soul into it. Great job I enjoyed every minute if the build. Thank you Doug.
Thanks, Tim. I don't mind sharing my creations with people who truly appreciate them. It's a win for both of us :)
Another great video. I've been watching for years!
Thanks, Doug. Glad to hear it :)
New subscriber. I'm thoroughly loving your content (and am currently binge watching most of it). I haven't played with tubes since the prior millennium, but you've given me the bug. Gotta say my favorite part of this one was the cat hairs on your computer monitor (mine now has finger smudges from trying to wipe them away!).
Greetings, IK. Once you get to know us better, the cat hairs will not be a surprise :)
Uncle Doug is a Genius
Aw, shucks, Sid. You are too kind ;)
Beautiful amp. It will become legendary as one of the highest quality custom one-offs in history. This vid series will be used to establish the value of this amp in a few hundred years!
Tell us more about the guitar. Esquires are single pickup guitars, aren't they? There's a 1963 all-original for sale right now for 34 thousand dollars...
Awesome video series, Uncle Doug.
Thanks so much for your very kind words and flattering prophecy, JZ :) All Esquires were routed for two pickups, with only one installed and the other hidden beneath the pickguard. This makes it possible to add a second pickup without altering the guitar in any way, other than replacing the original pickguard with a double-cut (i.e. Tele) one.
@@UncleDoug Thanks for that. It would be interesting if you put a price on that one-off, hand built, custom designed masterpiece of an amp. It might realistically be priceless.
Thanks so much JZ. Even at minimum wage it would cost over $2K.@@AgentJayZ
@@UncleDoug Long after we are gone, and thanks to these videos being immortal, people will be bidding what we would think are unimaginable fortunes for your hand made works of art. Some billionaire in the future will chase after, and finally assemble a collection of all your scratch built jewels, and for comparison will also display the hand-built Grable you were so impressed with. I hope they all get played, and properly cared for until electricity is no longer used, or even available...
Wow ! Great Build, Thank you
Glad you like it, Bob.
An exemplar of instructional videos.
Thanks, Ross :)
uncle doug, good show because not a lot of youtubers build there own amps from scratch thank you for your time doing this 👈👺👀👀👍
Thanks, Ralph. Glad you lied it :)
"Do one thing, and do it well." You, sir, are the epitome of this philosophy. Although that's a little presumptuous of me since I don't know what else you do, LOL.
He builds some pretty cool hot rods too
Thanks, fellows. We do our best ;)
Man, that esquire was sweet. Amp sounds good too
Thanks, Joe :)
Nice work, as usual
Thanks, David :)
Coming at you.. from the tremolo capital of the world 😜
Just down the road from Reverb Junction ;)
Really nice, I love the point to point wiring.
Thanks, Michael.
Fantastic job Uncle Doug!
Thanks so much :)
Earlier today I was deciding what to watch on my day off work. It occured to me that I haven't checked in on what Uncle Doug has been up to for a while. I'm so glad I did. I've got a bear of an amp repair I need to get started thinking about (original first year model Peavey 5150 Block letter head). Between you and others on RUclips, real tube amps aren't magic and voodoo anymore. Time to start hunting down a bunch of caps and some discontinued potentiometers.
Thanks for watching, Chad. Best of luck with your repair project.
Point-to-point wiring can be an art form or a mess of spaghetti.
You definitely should be proud of your work, leave a "made by" note on the chassis.
Thanks, Mack. I did.....on the cabinet wall.
Thankyou Uncle Doug for all your do. I have binged on your videos this Christmas break. I have to keep studying for my P.Eng. CPD. (Continued Professional Development). So I watch your and others videos on tube theory. I also read books. I might even build one of the kits for fun. I did built an Audio Dummy load with meter over the break. Designing an amp would be fun using some different tubes from the common old favorites. Going through the load line and choosing a bias point for just the right amount of distortion or lack thereof. I wish I could do woodworking like you do. My attempts always end up dirty.
Greetings, Ak. We're glad the videos have been interesting and helpful. Best of luck if you do choose to design and build and amp circuit. Let us know how it turns out :)
Outstanding!
Thank you kindly!
Well done Uncle Doug. 🎸 👍
Thanks, Phil :)
Dear Doug a simple way to create more room on the 9 pin sockets is to half way fold back each pin, e voila' more room is created, which also avoids potential short circuits. It works for me.
It worked for me too, Vincenzo. Thanks for your input.
I have no idea about most of these videos but I really enjoy watching them. Its always good watching a master work.
Thanks, B. We're glad to hear it :)
Start to finish - Specf'ingtacular!! All of the workmanship is absolutely 2nd to none - a pure museum piece ! UD - thank you so much for bringing us along for such a fantastically great and fully accomplished project. The person receiving your work of perfection is one VERY lucky person.
Wow...thanks so much, Skip :)
Sweeet! Thanks Mr. Uncle, and Cats ; )
Glad you liked it, Lu :)
Thanks for a year of fun🎄🇺🇸✡️✝️
Thanks. Hopefully we'll have many more :)
Nice work as always. Thanks uncle Doug
Thanks, Daniel :)
That episode has a lot of info to take in, Especially the new grounding and smoothing circuit. I m going to have to watch it again and make notes. Thoroughly enjoyed this build Doug. What a peachy amp, along with the Esquire tones. That was a treat. Customer must be thrilled.
Thanks for appreciating all our work, Alex, and for your kind words. He was :)
This build is sooooo clean. I so highly appreciate all the information given over the years. I´ve learned soo much already, just from your vids, reflecting in repairing amps myselves. Please keep up the good work. Love frome the Netherlands and happy holidays
Thanks so much, Eric. We're glad to hear that our videos have been helpful :)
Just wanted to wish you a blessed New Year on this Jan 1st 2024. Thank you for your devoted efforts to teach us all valuable information about electronics. Stay blessed my friend. ❤️✌️😎👍
Thanks so much, RF. Will do.....you too :)
I must say this build turned out really nice. That chassis is a real masterpiece both topside and under deck. A real solid performer as well. Looks great and colorful with all new components & tubes. Be proud of this one, UD!
Thanks so much, Daniel. I, and hopefully the owner, agree with your comments :)
An hour well spent for me this morning! Thanks, Uncle Doug!
Glad you enjoyed it, Ken :)
BBeautiful build uncle Doug.
Thanks, Monty :)
What a brilliant teacher Uncle Doug is, makes things a lot easier, than gobs and gobs of technical theory. Well done Uncle Doug and thanks so much for all your videos sharing your know how.
Wow.....Thanks so much, Polly. :)
Magnificent Doug. A super effort, keep it up
Thanks, Ex. Will do :)
One of a kind, fully documented masterbuilt, amp by Uncle Doug. I would proudly own this amp, if it were mine!
Thanks for the nice comments, TFE :)
Great sound for a small cabinet!
Thanks, Fred.
Bravo, Doug!
Thanks, Chris.
That turned out very nice. Sounds great too!
Thanks twice, VC :)
Great video! From your fans in New Mexico with the green enchilada casserole.
Thanks !! That's exactly what we had for Christmas dinner.....with Hatch green chilis :)
Thank you Uncle Doug for another wonderful series, it takes me back to the very first amp I built witch was an Angela Super single ended version of a Princeton circuit that worked first try leaving nothing the fix but a pesky polarity switch that would blow the fuse if switched while on but would work if you switched it when off, I deleted it!
You're welcome, Jeff. Glad you enjoyed it :)
I really dig the sound of the low gain input. The amp sounds killer. Super nice job building it.
Thanks, BH. I agree, the low gain input plus increased volume = a bit of "hair" :)
Thanks buddy. So cool to see you again.
Great work as usual.
Likewise, Aden. Thanks :)
Awesome build UD, thanks for sharing & a Merry Christmas to you & yours!
Thanks, James. Likewise to you and yours :)
I had reservations of the power trans being so close to the speaker magnet. I was wrong. Nicely done.
You're not necessarily wrong, Jerry. It's just that I have never had any issues due to their close proximity.
Beautiful! What an awesome build! Thanks for sharing.
It's a pleasure to do so, T.
Uncle Doug you are truely a genious and I greatly envy you I would have to live two more lifetimes to understand all that you show us out here in RUclips land . Thanks for such great videos and I must say most of my projects I always have to go back and redoo a few things and a few times at that. thanks for the drone footage of the boarder my how Elpasso and Huarez have grown . I was unaware though that Fender Esquire ever had a neck pickup maybe it was an option or my info is not correct
Wow, thanks so much, 20x20. The neck pickup was added in the factory-routed inlet present on Esquires.....just like Bruce Springsteen did.
Beautiful! ❤
Thanks, RM.
What a great build!
Thanks, Zach :)
Nice! That thing looks like an old military radio inside.
Thanks, Alan.......I guess ;)
A great series, Doug. Thank you much. Happy Christmas to you and yours.
Thanks !!! Likewise to you and yours :)
Such an absolute damn treat to see this! Thank you for bringing us along, Uncle Doug. Cheers to you and yours!
Thanks so much, S35. Glad you enjoyed it :)
Sounds and looks great, Doug. Always a joy to watch your process.
Thanks so much, GM :)
Great job! The amp turned out fantastic. My experience scratch building amps is much like yours. Dive in and Fix as you go. My results usually were not as good as yours but it is an excellent learning (and humbling) experience. Kudos!
Thanks, FBH. We're glad the videos are helpful :)
Sounds great, looks great! Thank you for taking us on this creative journey. The air tour of Hueco Tanks and area was fun too.
Thanks, Andrew. Glad you enjoyed the flight :)
That was the best hour of this week!!
Sounded great UD.
Loved the 3 part and detail that was in it 👍
That's great to hear, RGB. Thanks !!
Always a great pleasure to see your meticulous work and to hear your dulcet tones.
Thanks, twice, Frank :)
Well Done Doug, Merry Christmas from Wisconsin!
Thanks, KB. Back at you from West Texas :)
Loved the music on the scenic trip. Well done!!!
Thanks, CF :)
Excellent series and an sounds like an outstanding build!
Thanks twice, V.
Looks like a thermionic masterpiece.🤠
.........and hopefully sounds like one too :) Thanks, FH......I say, thanks.......he's a good kid but he just doesn't listen ;)
Excellent work as ever Unc ;-)
All the best for the festive season.
Thanks, Steve. You too :)
Happy Friday. Looks amazing and sounds fantastic! According to the internet, the next full moon will be Dec 26 at 10:33 pm. We should all howl in unison that night to salute this spectacular addition to the family of amplifiers! We loved the kitty cat pictures and drone footage!
Thanks so much, Wyo :) A very Merry Christmas to you all :)
@@UncleDoug Merry Christmas to you and yours too!
Excellent build...sounds amazing.
Wishing you and family Merry Christmas and Happy New Year!!!
Thanks so much, Doc. Likewise to you and yours.
Great program Uncle Doug! I like the problem solving. Thanks for recording your thoughts throughout the video. I have to admit, my pucker factor was pretty high during the final shaping of the chassis... No different than finding out your power steering pump doesn't clear your freshly powder coated hot rod frame and having to hack in a relief! Sounds great!!!!
Thanks so much, Greg. Excellent analogy......I'll bet you liked the air grinder being used on the tender little arc of sheet metal ;)
@@UncleDoug I was hoping you'd break out the plasma cutter. :D. In all seriousness, I was trying to solve the problem before I saw what you did... Too thick for hand snips, no clearance for pneumatic shears, air saw is out, plasma is too messy... I was left with roughing it out with the whizzer wheel, then cleaning up with a needle file or die grinder. A sanding drum on a drill press was another thought I had for the cleanup.
The solution initially puzzled me too, Greg, but fortunately it all turned out OK :)@@GregsGarage
Wow, that thing sounds amazing. This was such a fun build to follow along with. Thanks a ton for sharing all of this. Love it!
Thanks, JL......glad you enjoyed the series.
Thanks so much for all you do, Uncle Doug. I've learned so much from you
You're welcome, Matthew. That's great to hear :)
An all around fantastic video. Loved every minute. The amp sounds incredible, really incredible! WOW!
Thanks so much, Michael :)
Great series!
Thanks, Norman :)
you've crushed it again. What a beaut!!!!
Thanks twice, Rick :)
GREAT job Doug. Very interesting grounding. Have a Very Merry Christmas!
Thanks, Dom. You never know what will happen with a new method, but I thought it worked out quiet well.
An epic and beautiful project.. ✔️✔️✔️👏🏻👏🏻👏🏻👏🏻
Thanks so much, Jennifer. High praise indeed from someone with your experience and technical acumen :)
Hmmmm.. Tremolo Strip.. that was my girl mercedes' signiture move at the Slippery Chalet. Ahhh memories... 😮 Greetings from yootoob land!
Better than the "reverse audio pot" move my girl had ;)
Amp sounds fantastic!
Thanks, MNB :)
As old Hank would say "You Win Again".
Thanks, Steve.....and so does the owner :)
Epic!
Thanks so much, Craig. I value your opinion and appreciate your input.
A proper job Uncle Doug - love your work.
Thanks, Mick :)
This series was really interesting - thanks Uncle Doug!
Glad you enjoyed it, AC :)
Really love the P2P philosophy.
Thanks, HJ.
Hey Uncle Doug, good to see another video. Sounds great.
Thanks, William :)
Simply Awesome!
Thanks :)
Great video series and a fantastic outcome. Loved watching the build process and hearing the tone of the finished amp! The snippets in between the build process were also really fun to watch. Thanks so much!
We're glad you enjoyed the series :)
That's a nice looking chassis Uncle Doug. A real jewel and Merry Christmas to you and yours.
Thanks, Mr. P. Likewise to you and yours :)
Wonderful explanation! Thank you Uncle Doug
Thanks, David. Glad you enjoyed it :)
excellent work, Doug and education as well!
Thanks, MB :)
I always learn a lot while watching your videos. Thanks for sharing your work.
That's great to hear, Rohan. You're welcome :)
That is absolutely a work of art! very impressive, Uncle Doug!
Thanks so much, David.
Uncle Doug you sir are a National Treasure! A very Merry Christmas and a Happy New Year to you and yours.
Thanks, Lynn :) Likewise !!
Thanks U.D.
Gonna have to catch up on this,. You always do such cool amps.
Thanks, CSM :)
Grateful for these vids. I WILL someday use them to build my own. Thank you UD. Have a very Merry Christmas, To you and your kitties. 🎩🎄🌄
You're welcome, RH, and best of luck with your project. MC to you all :)
Great amp! Great guitar! Yes very encouraging!
Glad to hear it, Victor :)
Sounds great, Doug!
Thanks, Chris.
Merry Christmas and a Happy New Year Uncle Doug and the family! The amp sounds incredible, you never cease to amaze me.😊 Thank you for your many talents.
Thanks so much, Bud. MC & HNY to you and your family :)
@@UncleDoug Brymstond was my bands name, but my nickname is Bud or Buddy
Noted and edited.@@MrBrymstond
This was an excellent build, great results, the owner should love this amp
Thanks, Rick. He has the amp and loves it :)
That was a lot of work but well worth it. Fantastic results and an excellent video too.
Glad you enjoyed it, Phillip.
My gosh uncle Doug! You really knocked it out of the pzrk with this build. That little beast gets the kind of sounds an tones i have been seeking for years to obtain at low volume. Also thank you so much for including the holiday wish segment from all the kitties. Merry CHRISTmas from my feral kits to you an yours. You have encouraged me to seriously dig out a dead amp i have that uses i believe a 12bn7 for its power tube an try to make a point to point circuit out of it as it somewhat got me those sounds at a tv set volume. Thanks again for this epic series.
Thanks so much, SC. Actually the volume of our audio demos is much higher than you might assume from the recordings......but the Suprinceton definitely did provide great tone at moderate volume, largely due to the NFB being switched off.
@@UncleDougI'm using a modern fender super champ, also running 2 6v6. I know 10 watts is supposed to be considered "low output" but to get a good tone you sure have to crank it until its pretty damn loud for home use! I must be gettin old!
We found that by using the low-gain input with the volume double that with the high-gain input, the resulting tone was quite nice. @@stratcat4450
