1955 Fender Tweed Harvard Amp.....Not All Amps went to Princeton :)
HTML-код
- Опубликовано: 29 авг 2021
- This video features a 1955 Fender Tweed Harvard Amp......quite rare and in very nice, original condition. As usual, we check it out cosmetically, discuss the place that it filled in the Fender line-up, and then overhaul the circuit for maximum performance with minimal disruption of originality. Despite replacement of rectifier and output tubes, filter caps, coupling caps, selenium rectifier, power cord, etc. the plate current remained quite low (6 mA), implicating the power transformer as the most likely culprit. In order to preserve originality, however, I extensively modified the bias circuit to achieve a PC of 31.5mA with a relatively low PV of 215 VDC for a PD of 6.8W.....approximately 60% of max. The audio demo seems quite acceptable with good tone and volume, but a final determination on the PT will be left up to the owner.
NOTE: Although the Harvard circuit normally operates at a relatively low PV of 325VDC (compared to other Fender circuits), this circuit's PV is about 100VDC below this level. I have no idea if the seemingly-original power transformer is incorrect (for foreign use?), slightly defective, or operating properly (with no other Harvard circuits to compare).

Don't be fooled by Uncle Doug's soothing baritone voice, he is the best teacher you will ever have in your life.
I wish we had such great teachers when I was an engineering student.
Uncle D would have gotten me into engineering, period.
Thanks so much, Beta. My teaching career was actually at a much lower academic level........middle school math and science.
My middle school (or what we call "comprehensive school" here in the UK) maths teacher probably had a bigger impact on my life than any other teacher, including my high school (sixth form) teachers or university lecturers.
@@chriswareham I believe it, Chris. I chose that grade level because it has, as you have said, the ability to make lasting impressions.
OH I LEARN A LOT BY ACCIDENT.
I just wanted to say uncle dougs maybe the best,underrated youtube channel of all time.
Thanks so much, Akram. We definitely have the greatest viewers on YT :)
I watch him just to watch him. I'll never afford an old amp. I'm pretty sure all mine have PC boards.
@@davidfellows6250 We're glad you do, David.
@@davidfellows6250 some of them aren’t that expensive! And if you’ve been paying attention you know how to replace filter caps, look around… these old fender amps are fetching really high prices
@@slothtronix3047 I've got five amps that I like, I don't play professionally any more so I probably won't buy anything eles eleven guitars, three pas and five tube amps for a guy noodling...... live your videos I've learned a lot watching and listening to your cats play thanks Uncle Doug.
Great to see you are ok…I and a lot of other people were worried about you.
He has a second channel called Uncle Doug's Hot Rod Garage.
We appreciate your concern, David, but we're only getting started ;)

Great to see you back uncle Doug, we’ve been missing you.
It's good to be back, Steve :)
Hooray! Uncle Doug's here, been well missed over these last weeks.
Thanks, BN :)
You never fail me. Just no substitute for your presentations. Overview, history, schematic approach and problem solving. Low voltage fender is an oddity. :p Not usually a problem you would find. switching rectifiers could boost it, but if it works well with less, maybe that is a plus.
Thanks so much, AZ. I agree......Fenders generally run rather high plate voltages, and this amp is just the opposite. Since it's my first Harvard, I had nothing to go on other than the schematic......but to me, tone is the bottom line, and this amp sounded just fine to me.
RUclips has a ton of amp techs, some great and some not so great, but Uncle Doug is the Indiana Jones of tube amps. I don't know anyone who can match his depth of knowledge, expertise, skill or teaching method. That's not just my opinion either. His name is highly respected in amp forums with members referencing links and sharing tips from his videos library.
I hear he's also pretty good with hotrods. ;-)
@@Slugg-O Wow....thanks so much, Randy. We are humbled by your very kind words. Even Jack is blushing ;)
@Uncle Doug as the amp was overseas, you never know what type on AC power abuse the transformer may have seen. Is it not a bit risky to leave the weak transformer in circuit?…
“Molest your wife, and give your daughter hickeys”. I’m dying!!! LOL.
Another wonderful video. So glad you’re back. The absolute best channel on RUclips!
Thanks, Scott. Now I've given all the teenage girls in YT Land an excuse for those hickeys.
The "and goodness knows what it does to the dog..." got to me....
@@OzziePete1 I dare not speculate ;)
It certainly a slippery slope once you start playing around with that selenium!
Everything they say can happen will happen no matter how much you think it can never happen to me.
Selenium destroys families. The good news is it doesn't have to.
@@southboundsuarez9832 You're so right, SS. I knew a man whose entire family was kidnapped, held for ransom, and then sold into slavery by a selenium rectifier. To make matters worse, he was aided and abetted by a Death Capacitor. The carnage MUST be stopped.
Welcome back and what an awesome lesson in the reworking of the 55’ Harvard!! What a true jewel of an amp.. and it’s a Lupe to boot!! Thanks again Doug and here’s to your health and well being!!
Thanks so much, Luth. It's great to hear from you ;)
Yales went to DC, nice one Doug.
Thanks, Craig ;)
@@UncleDoug That Yale joke was amazing, and delightfully subdued in it's delivery.
@@dudedavid522 Glad you liked it, D :)
My dad was in MacGeorge Bundy's Yale class, and also ended up in DC (as opposed to AC [Atlantic City?]) but not in the govt (thankfully!) And yes, it was a LMAO moment in the video! :-)
Great to see ya back Uncle Doug. I’m Looking forward to viewing this after work. I hope you and your entire family are doing well. 🍺🍺 Cheers.
We are indeed, MF. Thanks so much. Our best to you.
Welcome back Doug!
Top notch video. In depth, detailed. Well done. Thank you!
Thanks so much, Reggie :)
Doug, your craftsmanship and respect for the hardware you work on always brings a smile to my face.
I'm glad, Rodney. That's our goal :)
There are a few videos available on RUclips taken from old movie film, obviously, that show various Fender employees at work in the mid-fifties. You can see ladies soldering with gigantic clumsy soldering irons, and when you look now at the beauty and cleanliness of Lupe's circuitry build it's quite a tribute to her skill.
This was an unusual job, and we are fortunate to have Uncle Doug to point out some variations from the norm that are not so easy to spot or pinpoint.
Great work, Doug !
Thanks, Richard, for both the nice comments and the tribute.
welcome back UD the gold standard in amp repair,,,technical as well as visual
Wow....thanks so much, Tom :)
So glad to see another video! I've missed seeing you, Ollie, and Jack! Glad you're back!
Thanks, Russ.
I love your work, sir. I just turned 40 and I hope to continue this amazing educational tradition you have given us.
Thanks, Nick. You're a youngster.....just what we need in this field, to carry forth the proud tradition of tube electronics.
You’re doing the world a favor, good man. Another beauty returned for service to the music community. 🙏😊
💪🌎🤘
Thanks so much, Jim :)
Hey Uncle Doug! I was especially glad to see you work on a Harvard amp. I made one of these from a schematic, and it actually worked! It sounds sweet at low volume, then breaks up only OK before it sounds rather harsh. The volume never amounts to much like some other amps. I heard that Steve Cropper uses a Harvard amp at times.
Greetings, Butch. Thanks for sharing your experiences.
Another amazing video! I love the care you took in preparing the replacement caps. The single coils sounded great in that old amp. Thanks Uncle Doug!
Glad you enjoyed it, Rohan :)
Sir you just made my day when I saw the notification on my phone that you posted a new video! Had to watch it right away! Thanks for all you share with us Uncle Doug.😎
My pleasure, SPL. I hope you enjoy the video :)
I always enjoy watching a monologue from Uncle Doug! A pretty sharp guy and “seriously” funny, which I get is a contradiction, but he is clever with his humor and his sarcasm is always dead on perfect! (All the Yale amps ended up in Washington D.C.!!!😆👌Thanks Uncle Doug for another winner!😎
You're welcome, Todd. Glad you enjoyed it :)
Thank you uncle D, we appreciate your expertise and time.
....and I appreciate your nice comment.
Fantastic video; thank you Uncle Doug. I really am relieved when I see an amp shipped to you well packaged....
Thanks, Tom. As was I......it was beautifully packed and easily re-packed for return shipment.
Great to see you back Uncle Doug and another fantastic restoration video. Thank you
The pleasure was ours, Pedro.
UD...I must say I had to stop at the point where you describe what a selenium rectifier would potentially do to your wife, daughter and dog...not only is this the BEST ampaholics channel...it is also the best comedy channel on RUclips!! Thank you SO much for sharing your vast knowledge of vintage amps (I had never heard of a Harvard) But also for making it entertaining and so much fun to watch!!
Thanks for your kind words, Jack. We really try to keep things amusing.....for both our sakes :)
@@UncleDoug One day someone who has no idea of the electric/ electronics industry of the past will hear this and try it . (Unless its only those of us that did Physics O Level that watch these YTs)
@@highpath4776 I hope so, HP. Thanks :)
What a beautiful amp! Also great video and description, as always! Just wanted to note that a GD stamp would indicate April of 1957.
Thanks for the info and nice comments, Grant.
Incredible stuff as always! These Harvards are criminally underrated. Thanks Uncle Doug 🙏
Our pleasure, Anthony. This was a learning experience for all of us :)
Nice to hear your voice again. Tips are good, I always learn something from your videos.
Thanks, Phil. That's our goal :)
As you went through your analysis, questions and ideas would occur to me and within seconds, you would answer them. I couldn't figure out what kind of voodoo telepathy you were using on me. Then I saw the fuzzy dice at 34:56. Bingo. I must get some for my repair bench without delay. Surely that will move my repairs at least a smidge closer to your league, Uncle Doug. Thanks for another very helpful video!
So glad to hear that we're on the same wavelength, Scuzz. The fuzzy dice rule !!!
Voodoo telepathy for sure! In my case, I was just starting to holler "what about the 5Y3? You didn't test the 5Y3!" and right away Doug mentions he subbed out the 5Y3 and it made no difference.
Why did I have to click on this video?! Now I have to add yes another two rare amps to my dream collection. Harvard and Yale fenders.
Good luck with the Yale model, Jordan. Most of them don't work well ;)
@@UncleDoug Dont they come with a 2 year cooling off period and a 4 year guarantee ?
Man that's one clean amp for a 1955 Harvard. Those are very nice amps! I built a Harvard clone a couple of years back and loved how it came out. I plan on doing 2 more this year. Another wonderful video Doug!! Thank you sir!!!
Thanks for your very nice comments, Cary.
Wow! What a cool amp! I did not know there was even such an amp as a Fender Harvard. That amp is a gem for sure! Thanks for another learning experience video!
Glad you enjoyed it, Wade :)
Re loss of volume due to low plate voltage: it's worth remembering that human perception of volume is logarithmic (hence audio taper, ie logarithmic pots). The output of an amp needs to be increased 4 - 5 -fold to perceive it as being twice as loud. A 100w amp isn't subjectively any louder than a 50w. Thus a 40% drop in volume wouldn't be perceptible. And would explain why this beauty still sounds LOUD.
Excellent analysis, FP. Thanks !!
If I remember correctly, it take 10 times the power (10dB) to be perceived as twice as loud. That's why some high fi reviews have moved away from specifying power in watts to using dB as it is a better match to how we perceive volume.
@@russellhltn1396 I believe you're correct, Russell.....and some people argue that "sound pressure" is really what counts, adding even more confusion.
Finally........ another Uncle Doug video....... I have been waiting for this :)
We hope you enjoy it, Richard.
@@UncleDoug I enjoy all of your video's. Thanks for taking the time to make them. We all appreciate it.
@@rgbplumbinghilton That's great to hear, Richard.
Good Video, how could one not love the potential sound of an old fender amp.. Looking forward to more!
Thanks, Brian. We are too :)
Very few things are finer than finding a new Uncle Doug video. Watching the resuscitation of a cherry classic amp is priceless. Thank you Uncle Doug! I hope you and your loved ones fare as well as humanly (and felinely?) possible.
Thanks so much, Michael. We are doing ridiculously well. Hope you are too.
You should offer electronics classes in your garage... you have more knowledge and a way to deliver it in such an easy-to-understand method... you are just the absolute best. Love your videos!!
If I were younger and had more time and energy, I would consider creating an online electronics course......but, alas, I am old and weary ;)
He kinda does, Rick. There's an excellent selection of subjects in his list of videos.
@@iroffman Thanks, Kort. I tend to agree. The videos are all created from an instructional viewpoint.
@@UncleDoug oh, understood... heck, the animals alone are a full-time job!! : ) Let alone the auto cruises, etc. ...and yes, your videos are EXTREEMLY educational, which was my original post. Thanks for everything you do!!
@@rickbaker4571 You're welcome, Rick.
Don’t ever leave us hanging like that again I know it’s selfish of me but do know what it’s like to check u tube every day wondering what happened to my uncle 🤨 great to have you back
Thanks, Kevin.
I learn so much from your awesome vids, Uncle Doug. You helped me get my AO-35 conversion back into action - dang filter caps! Thank you for sharing your wisdom, Sensei.
Glad to hear of your successful repairs, PM. Keep up the good work :)
Always exciting to see when you release a video! Excellent video once again, I always learn something new.
That's good to hear, Pappa. We hope you enjoyed it.
Great video as always. I have a 56 Harvard, it’s a great amp. I’d be happy to grab any measurements from mine if you need comparison data. I did have to replace the output transformer when I got it, the original was shot. I’m wondering if the OT could be involved with the problem that you encountered, it is in series with the plates. I didn’t see a transformer shot in the video, but it would have been interesting to compare with my original photos. Thanks for all you do, a lot of folks learn good amp restoration practices from you. Dave
Thanks so much, Dave. Have you measured the PV and PC in your circuit?
@@UncleDoug I measured the 2 power tubes and got 22.5 and 32 mA with a plate voltage of 310 volts. They clearly aren’t matched tubes but they are vintage and they sound great :-)
@@DaveGVideo The values are conservative.....so if the sound is good, all that's left to do is enjoy the amp :)
Wonderfully Brilliant work as always, thank you ! I have been trying to decide what to build for a first ground up build ; and as soon as you struck the first chord in Crow's "perfect mistake" I made up my mind. It was a throwback to "name that tune" and I had it in one note! I could have won at least $10 ;p., that is the perfect thing to turn a burned out hot rod deluxe ( typical leaky CI caps and 5w resistors on the board and hot diodes too; the pcb is probably pooched also ) into, just like your 5F5 champ video ,only bigger. How do you spell that sound that a wide smile makes? Thank you for the inspiration ! I actually have paying jobs going now!
Wow....thanks so much, Griffin. Best of luck with your project.
Thank you for giving us yet another entertaining, informative and wonderful video Uncle Doug! You are absolutely the best!
Thanks so much, Thomas.
As always Doug an excellent vid. Informative and very entertaining. I'm already looking forward to the next one. Thank you.
Thanks so much, Colin.
Uncle Doug, what about using a beloved GZ34 rectifier to get the plate voltage up a little more? Or even one of those octal socket plug-in solid state rectifiers from Weber? That way, there are no permanent modifications to such a rare jewel.
Excellent suggestion, Andrew, and one I never considered. It would definitely have had a "positive" effect on the B+.
I've been waiting for YEARS for Fender to do a Skull and Bones model reissue. ;)
The few they made were all sent to Washington DC, where they immediately quit working, hung around for 20 years, and now just collect dust and huge pensions.
I just made a post about the S&B yale comment.
And now i see Guitaroligist and Uncle Doug on the same thread.
I couldnt help but make a comment.
This is like the comment version of photo bombing famous people :)
Whats up brad?
Excellent video as usual UD and great to see you again.
Thanks twice, JT.
How did I just find this? Uncle Doug, you are amazing! I own a 1959 Harvard, and you took me to school. Thank you!
We're glad you found us, Zac. Welcome aboard :)
When nothing else in the world makes sense....there's Uncle Doug.
My wife would disagree, Shaun.....but thanks ;)
I would have checked the bias before replacing that “6.8K” resistor in the bias supply. You ended up having to diddle the bias voltage anyway.
The 6G10 Harvard was very similar to a Tweed Princeton. A single-ended amp with only 1 6V6 power tube. In fact, the 6G10 schematic is identical to the earlier Princeton 5F2-A schematic. As far as I can tell, the only difference was a larger cab to accommodate a 10” (vs. 8” for Princeton). Transformers may have been different as well (probably were). I do wonder which Harvard Steve Cropper and others were playing.
Steve used the p/p version
I did check it, Chip, which is why the bias voltage had to be "diddled".
I like working on old radios and got a lot out of the troubleshooting methods you used! Thanks for posting.
That's great to hear, TE :)
Good to see another amazing vintage amplifier on your work bench. 🙌 Good to see you Uncle Doug!
🤟😆 Rock On!!
Thanks, CTE. It's good to be seen :)
I've found often that incorrect voltages from PTs result from partially shorted windings which generate heat and can fail dramatically including high voltage on the chassis as it shorts through the transformer case. Time for a replacement (preferably a rewind of the original!)
Yeah I would worry about catastrophic failure of that PT…
Thanks for sharing your optimistic opinion, Max. Hopefully, your dire predictions will not occur ;)
@@UncleDoug Murphy's Law?
@@silasfatchett7380 True......humanity's curse.
@@UncleDoug how can you have a partial short ? an insulation breakdown on certain currents ?
Well, Thurston Howell III always had disdain for Yale men as uncouth savages, but this Harvard might make him blush.
Let's hope so, GM ;)
You channel is incredible. An absolute amazement for a tube enthusiast like myself. Thank you thank you thank you!!!!
Wow.....you're quite welcome, LS. I definitely agree with your screen name :)
Great to see you posting again... its been a while. And man what a video. I've been kinda jonesing for a tweed amp. This little guy sounds great, thanks to your fine work. :)

That amp sounds great. I'd play that all day. I do love those small fender circuits! Thanks Doug.
Thanks, C :)
Back again, Doug!, and, as ever, great and nice job and description. I love this gem!. And I agree with you regarding the power xformer. But after all, it sounds and looks nice. I am one of these which change selenium rects once I see one (my latest one was in a Fairchild 670 compressor I own). Happy to know about you again, and best regards from Spain.
Thanks so much for your very nice comments, FW. Likewise on the regards :)
Nice sound Doug. Very smooth. Glad to see you back.
Thanks, Jim :)
You are one of the funniest people on RUclips, I swear. Me and my boyfriend thoroughly enjoy every single minute of every video you do and have gained a wealth of knowledge from them. Thank you Uncle Doug
That's great to hear, Sam. Thanks to you both :)
Amazing Uncle D! Hope the owner likes the care that was put into it!
Thanks. He's a nice fellow and I'm sure he does, LL.
I came back to watch this one a second time. It was a real nail biter when I thought the vintage power tranny might have to go. I gasped. Luckily, this little gem sounds GREAT with that lower plate voltage. Gives me hope for humanity in all sorts of ways. What a great journey. As always, Uncle Doug... your work takes me away from all the cares of the week and gives me an adventure I can use.
Thanks for the very nice comments, JB. We're glad you enjoyed it :)
Amazing video once again! You've been missed in the RUclips Land. Mary Jane's Last Dance is a great tune to test an amp. Looking forward to the next one
Thanks so much, Alexis.
WOW....amp sounds great.....one of the best vids so far......p.s. - also glad that you are back ! ! ! ! I remember those selenium rectifiers back when I was building ham radio gear back in the late '50s/early '60s.
Thanks so much, Tom :)
Even though I have repaired my last tube amplifier I am addicted to your mindful and additive channel. I have been cured of excessive amplifier purchases and have decided to transfer my addiction to playing guitars. I am also cured of buying more guitars then I will ever be proficient at playing. Love your channel
Glad you enjoy the channel, Doug. It's good that you have ended your two bad addictions and kept the good one.
Seeing an Uncle Doug video post alert on a workday morning presents a dilemma for me. Put off starting work or watch the video? Another brilliant video Uncle Doug. Thank you.
Watch it at work, Paul. I have a special arrangement with your boss ;)
Wow Ultra Rare Fender all right..! Long time no hear from you Doug....So great to hear your dulcet, witty tones again. I'm beginning to see much more clearly after following and watching all your videos.. What a fabulous amp Doug, so much history and great fix..Ed..uk..😀
Thanks so much, Ed. A big incentive for each of our videos is hearing from great viewers like you.
It’s great to see you again and your videos.
Thanks so much, Denver :)
I've never heard of the Harvard - it was great to see it. Your compromise to save the original transformer was a great idea.
Glad you enjoyed it, John.

Thanks, Ken. It is :)
I am so glad to see/hear you again. A day without Uncle Doug is a day that will never hit any high points.
Thanks so much, Jeff :)
Wow! The clarity and clean tone of this amp is amazing.
It sounds more like a blackface amp than a tweed, IMHO.
Hello Uncle Doug & Family, Wow, another Lupe built amp, how cool is that? Glad your all doing well, good to see you. Always a class restoration, great attention to detail. What a great tutorial and teaching, Thank you. Sure can't beat years of experience. The amp sounds great! Cooler temps and busy with a total interior up grade, mini split heat pump, windows, etc..Thank you for all you do, these many years past. All the Best from Oregon, Cass.
Greetings, Cass, and thanks for the very nice note. It's always good to hear from you.

Uncle Doug~ I would like to echo the legion of fans here with how informative and entertaining your videos are. Also, I am a videographer myself, and I really appreciate the quality of your videos...well-shot, good audio, clear and concise editing. And funny, to boot! I am a Hammond organ freak, and I've been trying to learn about the tube amps in those and in Leslie speakers, and your channel has plenty of crossover, so to speak. So thank you, and please do carry on!

Uncle Doug I don't know who else this may have happened to but luckily I was scrolling through you tube and seen the new video, I've been subscribed for awhile now and never got a notification that a new video was up,I only mention this since some of the other channels I subscribe to have had the same problem in the last few months and they have asked that we notify them about this so they can look into it and see why there subscribers weren't notified. Great video btw I have enjoyed all the videos you have put up and learned alot for m you and your attention to detail. Thank you Sir.
Thanks so much for alerting us to this problem, DD......and thanks for the nice comments.
Great to hear from you again Uncle Doug from your antipodean friends in interminable lockdown! You made all of the modifications in a way that I would have done 😜 (if I had the time and skills!) What a little beauty this amp is, it's a pity there aren't some clever individuals who can duplicate the look of those yellow astron caps with modern materials - I'm sure there is a niche market for that. My 12 year old son has recently begun learning guitar and loves playing my 1963 Fender Musicmaster guitar through a single ended 6aq5 amp I was inspired to make from one of your videos I am sure some years ago when I seemed to have more time! All the best Colin:)
Greetings, Colin. It's always great to hear from you. Agreed on the yellow Astrons.....they almost always need replacement. Best wishes to your son on his musical career. He's lucky to have a dad who can build amps for him ;)
What a great Monday surprise from the Professor. I learn something everytime! Plus, enjoying an laugh via your corrugated sense of humor as well. I did not utter warped, sir. lol After all... it is "tax'free" entertainment. Thank you... I needed an Uncle Doug fix.
