I know! My wife couldn't wrap her head around why i enjoy these so much, then she started loving to listen to him and she is not even a musician! I also steal many of his "Uncleisms"! One of my faves: we have wires hanging like a dis-embowled Antelope!😄
A few comments on the video: 1.) I say "6V6" instead of "6L6" at 1:11:20. 2.) Thanks to Robert Set for the opening musical montage and logo. 3.) We tried jumpering Ch. 1 & Ch.2 for the audio demo, but for some reason it did not record well. 4.) It should be noted that Jim Marshall himself did not actually build the amps.....this task was done by Dudley Craven and Ken Bran.
Uncle Doug is my favorite amp repair guy. His knowledge is very good and his attitude is the best. It is no wonder that people send him so many gifts. He is a wonderful human being. The world could use several billion people of his demeanor. The work displayed in this clip is highly commendable. Pretty much the norm for Uncle Doug.
that was Erie technological products they made world famous capacitors and resistors among other things... I grew up in Erie PA and remember that business on 12th St.
Uncle Doug getting a new video out means to stop anything, grab some tea or coffe and getting into yet another great repairing session with great humor :) I will need to get one of these Marshalls, some day...
Check out the new Marshall Studio amps... while they are PCB instead of hand wired, their build quality is outstanding. Fact is, Marshall could teach Fender (and others) a thing or two about amp design.
Stop anything and grab some tea to watch ? André, do you have a spycam in my living room that I'm not aware of ? 🤔 I was supposed to start working, but got « distracted » by Doug's entertaining offering 😂
Wow that tip on stopping the high frequency oscillation was absolutely fantastic. I really appreciate that. Thank you so much, I will store that in the old memory banks. Great stuff.
I'm just a guitar player. No electrical knowledge before finding your series of videos. I am always fascinated watching you work and explain all of the dark voodoo magic of electronics. Your attention to detail (respectful reverence?) towards this 66 JTM45 was awe-inspiring! I hit the thumbs up while wishing there was a guy standing on his chair applauding wildly I could trigger to let you know how much I appreciate your desire to always go above and beyond! Cherry custom shop work!
Congratulations Doug on achieving your 100,000 subscribers -you thoroughly deserve it. The knowledge and the humour with which you pass on that knowledge makes every video a treat. Thank you for all of the effort that you put into each video. Thought that you might like to know that our new puppy - Penny is totally settled in and is proving to be a fantastic little character. She has brought a smile back to our faces after all of the health issues that I have and continue to have. Take care and it’s great to see you and your animal family back.
I can't tell you how much I appreciate your tuition, passion, love, care and respect for the craft. You truly are an inspiration and my favourite educator in this field by far. The efforts you go to to bring us these videos and the knowledge passed on during them are truly appreciated. Thank you, really. Best, Scott.
Superb video Uncle Doug. Some very innovative cosmetic enhancements with the capacitors that preserve the visual integrity of the amp. So much so that I consider the film to be worthy of mention and inclusion into the Smithsonian archives. We took these amps for granted many years ago here in the UK, so nice to see yourself and others appreciating and maintaining what you rightly describe as 'Jewels'
It’s like I’m in a high school and I like the subject, but you’re the class after lunch and after 20 minutes I’m asleep. I’ve watched this four times now.
Uncle Doug, love the channel, your attention to aesthetics and electrical precision makes it “must-see TV”! Congratulations on reaching 100K subscribers! Next goal is 250K. We’re all pulling for you!!!
To be honest with you, I have never opened up an amplifier, however I love electronics and watch as many videos about different aspects of the subject as I can. I do love your videos because of the way you go into what is happening in a circuit and how each component can have such a drastic effect on the overall operation of the unit. Thanks a million for being one of my instructors, it's like being back in college once more, except instead of law, I am learning electronics!
Watching this makes me want to build a 45. In 1970 I bought a Marshall Major 200 watt full stack , talk about a wall of sound. Thanks for the video great as always.
I think it was Ken Fischer (Trainwreck Amps), formerly of Ampeg, who said he put Mullard KT88s in a Marshall Major and "sailed past the 300 watt mark".
I was lucky enough to own a '64 or '65 variant of this amp between 1969 and 1974 here in the UK. It had the Marshall name in a solid Perspex plate, and the knobs were the larger variety with brushed aluminium faces. Other than that, the amp here seems pretty much identical, with the weighty transformers and the KT 66s. I loved that amp, but it had a chequered history. I once loaned it to a pal, who forgot to connect the speaker cab and promptly burned out the output transformer. Then I had it stolen - twice! The first time it was recovered thanks to a diligent police detective and a pretty stupid thief. The second time, it was lifted from the band's van, and that was the last I saw of it. So thanks for the memories, Uncle Doug! Always love it when a new video appears.
I see super amp tech has been here. A sad, lonely down vote. I have a dilemma now, because I am not super motivated to work on a Friday before a holiday weekend and Uncle Doug drops some amp goodness on us. I think a long lunch is in order.
I love amps, but I'm not an electronics guy. 90% of the time I have no idea what UD is talking about, but these videos are so calming and stangely hypnotic...like watching Bob Ross paint.
@@UncleDoug It was originally an american company, but i found some information about the UK branch: www.ourgreatyarmouth.org.uk/page_id__455_path__0p3p41p.aspx
Highly doubt that it’s an original, most likely the cap would have been a Radiospares. Never seen an Erie in a mid 60’s Marshall unless it was a replacement.
The editing program cuts at even seconds, not fractions of a second, so occasionally a word may be truncated. I reviewed the video several times and only noticed this once or twice......which, hopefully, did not ruin the whole video for you.
This Watches so easily it is dePendant on our so knowledgeable host..We appreciated seeing your Jewels and hearing your Pearls of wisdom. We also saw a beautiful Chain of two amps in this video and they were Ringing so delicately by the end. Uncle Doug you are a Diamond.
Another fine amp repair video from Uncle Doug! Two landmark amps, a JTM 45 & a Super Rvb! So much to be learned from your electronix expertise. --> Thank you for your candor 😉
You're so good UD, I'm not going anywhere anytime soon. I can only see your channel grow and grow. Heck, you made me go from "hmm what, let's watch this simple thing again" to "caps are bad" and "thank God for the current limiter" before you've said it. I know your teaching works, because it works. And your ethics are second to none. You are an inspiration and a great place to take knowledge as far as needed: all the way. Thank you and keep at it my good sire!
Great to see this british guy fixed. Even after watching you repair a lot of amps, your videos keep the high level of entertaining and informative like the first video.
I wish you lived next door so i could learn to fix my old broken amps. Also so we could get to the breakfast specials since my wife never wakes up before 10 a.m. lol. Thanks for the fun vids, God bless.
Uncle Doug is a master of documentation. I have 3 hard drives with my life's work on them. I just finished a Fender 5F11 with the selenium recto. I used the 330K across the 56K and 1N4007 diode anode to the 10K. Bias set at -31.00 vdc. I love these videos. I have been doing repairs for 45 years +. Don't think you know it all. At times you will run into something stranger than fiction. It's the little overlooked things like a bad speaker,Bad Volume pot or tube socket pin that is corroded and will not clean up enough to even make continuity. I said to myself one day, (Why don't you make a file to scrap a preamp tube socket. I wound up using a D string from an acoustic guitar that perfectly fits most any preamp socket and cleans (Files) the socket pins as new. I had a 5E3 vintage amp that would not turn on the cathode feeding the 6V6 power tubes. All the cleaner Deoxit in the world made no difference. Problem found and solved with that D string.. I'll never forget that discovery! I still use it when in doubt.
I've got to tell you I'm severely burned out. But if I have 5 amps in here I just have to pace myself and especially parts orders. And worst case scenario of the occasional bad tubes new out of the box.
I am glad to find this channel. I am planning a couple of upcoming projects to keep my brain busy. Both being replicas of vintage Marshall amps. One being a jtm45 and the other being a jtm45/100. I want to be as authentic as I can be so great to watch these videos.
Excellent. The beauty of the current limiter is that it allows different bulbs to be installed so one can change the wattage limit drawn by the circuit. Super work Doug thank you.
When I saw that the old can capacitor had been replaced and left in the amp I thought to myself this is the perfect opportunity to learn how to restuff one. Thank you for doing it that amp deserved it and thank you for showing us. The bonus footage of the fender was exciting. Another great video brought to us by the Master.
With the JTM 45 amp all dressed up working great, new tubes I hear why the P-90’s are so sought after. So perfect sound out of them from bass, mids, trebles just cloud like greatness out of them. Totally equal in volume. ❤❤❤❤. I started watching your channel some time ago. This rebuild I heard a smooth transition right in everyway. I thank you so much for all the lessons.
Another excellent tour of the history and techniques of these ancient and incredible equipment. Wonderfully driven by his technical ability, teaching and passion for the profession. Thank you for sharing. Greetings from Brazil. Here is the radio station PU2SRZ 73 and good winds.
Uncle Doug, Bless you have always exceeded all of my expectations. Thank you for sharing your wisdom with us and keeping us safe!!! God Bless and Protect your Family!!!
@@UncleDoug I understand that you maybe don't have the speaker capacity to crank that thing, but if you get a chance...haha you just gotta hear it. A cranked vintage Marshall is an out of body experience.
This my old amp! Of the hundreds of Marshall's I've owned, this was the BEST Marshall I ever owned! Should have never sold it...lol. Happy to see it's pretty much in the same condition as when it left me!
Hi, I really enjoy your videos for many years. I wish I lived in Texas to talk you into letting me apprentice with you. I could learn more than I do from your videos alone. Thank you for your teachings. I've learned so much from you.
Hi Doug, you yet again have done it, I was having issues with my Dumble clone build. I was watching your video on Oscilloscopes and you had an issue much like mine where you had parasitic Oscillation and mentioned fender put low value capacitors between grid and earth on output valves ,well worked a treat now no more weird noises she sounds fantastic Thought i would share it with you as my wife is perplexed as to why i would want to do this stuff , BECAUSE ! To all you out there Doug is a wonderful teacher and an inspiration to me and many more. Thanks Doug it is people like you that make life worth living I really couldn't have done it without you. Nikk
@@UncleDoug Tell Ollie and Jack they are getting a very nice feel, strange I have watched so long I have been a part of them becoming talented musicians for Cats that is.
wish we had a doug in our country,so much love for his work..ive got over 20 amps of every era in my studio so where is doug when you need him.im starting to get good at repairs thanx to vids like this.even recap old desks nowadays..lovely work your a master
Thanks uncle Doug for the 2nd part of the video. The current limiter can really save tonnes of money as well. And in the first video, the sound of the JTM with P-90s is a killer. Wow! 💪🏻
I still meet a lot of people who love Marshall amps and have no idea that some of them are based off other amps. One guy when I said his JTM 45 is a Bassman of sorts he was like "Marshalls are nothing like Fenders" haha. Thanks for the video, thats a clean looking amp on the outside for sure. (Still watching video).
Who needs Netflix when we've got 76 minutes of Uncle Doug ?
Thanks so much, Giuseppe :)
Exactly!

Although Jim would frequently be covering cabinets in the early days and his signature can be found inside...

Our pleasure, RJ. I hope you enjoy them.
Very nice work Doug! The extra effort of installing the replacement cap inside the can is inspiring…
Thanks so much, Byron.
Yeah I like stuffing caps!
Proud to be one of those 100,000 subscribers.
Well, excellent video as always.
Thanks you Uncle Doug.
Thanks twice, Reggie :)
You are the man, Doug. Good job.
Thanks, LB :)
When I saw that the old can capacitor had been replaced and left in the amp I thought to myself this is the perfect opportunity to learn how to restuff one. Thank you for doing it that amp deserved it and thank you for showing us. The bonus footage of the fender was exciting. Another great video brought to us by the Master.
Our pleasure, Steve. Glad you enjoyed it :)
I never miss an Uncle Doug video.
Were honored to hear it, Peter :)
Above and beyond with that Erie concealment cap. Really nice work Doug👍
Thanks so much, Rob.
Great tones. Even on my phone speakers. I'm sure it's a million times better in person. Great video
Thanks, Jason :)
I really enjoy yer videos. Keep up the great work and videos. I'm 70 now and still jamming. Rusty in eastern Tennessee
Glad to hear it, Rusty. Keep up the good work.
With the JTM 45 amp all dressed up working great, new tubes I hear why the P-90’s are so sought after. So perfect sound out of them from bass, mids, trebles just cloud like greatness out of them. Totally equal in volume. ❤❤❤❤. I started watching your channel some time ago. This rebuild I heard a smooth transition right in everyway. I thank you so much for all the lessons.
You're quite welcome, Greg. Thanks for your very nice comments :)
Another excellent tour of the history and techniques of these ancient and incredible equipment. Wonderfully driven by his technical ability, teaching and passion for the profession.
Thank you for sharing.

Uncle Doug, Bless you have always exceeded all of my expectations. Thank you for sharing your wisdom with us and keeping us safe!!!
God Bless and Protect your Family!!!
Thanks, F1. Likewise to you and yours.
Uncle that sounds fantastic brother, you're a genius.
Wow....thanks, Harmon :)
Great video on a great amp. I loooove those old Marshalls.
Thanks, Gl. AS I am gaining some experience with them, I have developed great respect for their power and tone.
@@UncleDoug I understand that you maybe don't have the speaker capacity to crank that thing, but if you get a chance...haha you just gotta hear it. A cranked vintage Marshall is an out of body experience.
"wow Fanta orange" ! couldnt think of a better way to spend a sunday afternoon,thanks Uncle Doug!
Thanks for joining us, Ted :)
This my old amp! Of the hundreds of Marshall's I've owned, this was the BEST Marshall I ever owned! Should have never sold it...lol. Happy to see it's pretty much in the same condition as when it left me!
Wow.....it's a small world. Thanks for the input :)
Uncle Doug, thanks so much for the wisdom.
You're quite welcome, KD :)
Uncle, you are a genious.
You are too kind, Ulrich.....but thanks ;)
Hi, I really enjoy your videos for many years. I wish I lived in Texas to talk you into letting me apprentice with you. I could learn more than I do from your videos alone. Thank you for your teachings. I've learned so much from you.
That's great to hear, Steven. We're really glad the videos are helpful and informative.
Hi Doug, you yet again have done it, I was having issues with my Dumble clone build. I was watching your video on Oscilloscopes and you had an issue much like mine where you had parasitic Oscillation and mentioned fender put low value capacitors between grid and earth on output valves ,well worked a treat now no more weird noises she sounds fantastic Thought i would share it with you as my wife is perplexed as to why i would want to do this stuff , BECAUSE !
To all you out there Doug is a wonderful teacher and an inspiration to me and many more. Thanks Doug it is people like you that make life worth living I really couldn't have done it without you. Nikk
I'm really glad the oscillation elimination technique worked for you, Nikk. Thanks so much for your very nice comments :)
@@UncleDoug Tell Ollie and Jack they are getting a very nice feel, strange I have watched so long I have been a part of them becoming talented musicians for Cats that is.

You're welcome, Bob :)
Been watching your videos while I have been sick, very fun to watch! Your experience and knowledge shows very well!
Thanks, Jeff. Best wishes for a full recovery.
Oh yea! Time to sit back with a bowl of breakfast popcorn and enjoy Uncle Doug and Jack.
Breakfast Popcorn.....the breakfast of champions !!! Thanks, Raiden.
Thanks uncle Doug for the 2nd part of the video. The current limiter can really save tonnes of money as well.
And in the first video, the sound of the JTM with P-90s is a killer. Wow! 💪🏻
Glad you enjoyed the video, Shade.
Enjoyed the sound clips with settings at the end!
Glad you enjoyed it, M.
I still meet a lot of people who love Marshall amps and have no idea that some of them are based off other amps. One guy when I said his JTM 45 is a Bassman of sorts he was like "Marshalls are nothing like Fenders" haha. Thanks for the video, thats a clean looking amp on the outside for sure. (Still watching video).
Those people really need to do some research to clarify their thinking.
Took a long lunch break so I could watch this, Thanks Doug
Hope you enjoyed it, Martin :)
Yes I enjoyed it, I was beginning to get worried about you not posting for so long. Figured I'd have to email Jack and ask him what was going on.
