Super Nice 1967 Princeton Reverb: Overhaul w/ Tremolo Enhancement
Вставка
- Опубліковано 27 лип 2024
- This video features about the nicest, original '67 Blackface Princeton Reverb you will ever see. It was sent in by a viewer for an electronic overhaul, and the video follows the step-by-step process, including the installation of a new electrolytic "can" capacitor and enhancement of the Tremolo intensity. In addition there are two workshop sessions with the 1930 Ford Model A "Rat Rod"......to move the seat forward (so the pedals can be reached :) and to fabricate and test a pair of exhaust baffles.

Cleanest Princeton Reverb I've ever seen. Looks almost new.
Yes, inside and out. A real gem.
I thought it was a reissue at first.
Evets Nitram I got a Princeton RI and wish that they did not use a circuit board for all the components. I'm seriously thinking about ripping the CB out and going p/p wiring. the only issue is getting the original 3M RA pot in the tremolo circuit.
You would probably be better off buying a nice Silverface Princeton, Steve. They are virtually identical to the Blackface circuit and generally quite affordable.
@@evetsnitram8866 So did I!
We're the same age, Doug. I was 20 years old in April of 1967 also. In fact I owned a 1967 Fender Princeton Reverb. Bought it used after I got out of the army in '68. It was in primo condition. Later got a Twin Reverb. Good stuff.
Amen, brother :)
I'm another baby boomer that was 20 in '67. I'm not into playing guitar -- I prefer the electronic organ. I am (and have been) very interested in electronics. Thanks for the great video!
Dave
I'll be 60 next month. I'm the bottom of the boomers. Glad I'm not old like you guys.
@@wildbillhackett, I'm 61 and my body feels like it's been through the ringer. I may not technically be older than dirt yet, but it sure feels that way much of the time. Actually I was telling the youngsters who hang out over at Brad the Guitologist's channel, who grew up on the music of the 1980s, that not only am I glad to be a decade or more older than them, because I experienced better music in the early 70s but I wish I was at least five years older and that way I probably could have been at Woodstock!
@@taky2686 , although I did not actually see the band perform, I did see Rick Danko and Richard Manuel playing together as a Duo, maybe just a year or two before they died. Both suicides as I recall, sadly. Blues woman Rory Block was the opener for that show. When Brad the guitologist was discussing what a badass he was as a kid with his Michael Jackson jacket, around the same time frame he was talking about, I was going to see concerts by people such as Johnny Winter, James Cotton, Doc Watson, Leon Redbone, Al Di Meola John McLaughlin & Paco de Lucia, Steve Morse and the Dixie Dregs, Pat Metheny, Jean-Luc Ponty, the Jan Hammer Trio, Stephane grappelli, Taj Mahal, Sonny Terry and brownie McGhee, Elizabeth Cotten, Marshall Tucker Band, The Grateful Dead, the Police, and so on and so forth. I pretty much hated most of the music from the 1980s, and although as they say hindsight is 20/20, I wouldn't have wanted to grow up in that decade for all the gold in Fort Knox. Hell, if I was 10 years older, I probably would have hitchhiked my way out to California to be at the Monterey Pop Festival! I could have been at Woodstock, I was just a couple years too young for that one. Of course, on the plus side of the column, I was just a little too young, going a little too late, to get shipped off to Vietnam. Anyway, I sure am glad I didn't grow up thinking that wearing a Michael Jackson jacket and imitating the moonwalk was the do all and end all of musical culture. And Michael Jackson's Legend doesn't look so good nowadays anyway.
I was working in audio stores selling and installing Hi-Fi equipment in the late 70s and early 80s, and doing nightclub sound system work on the side, and when people started listening to Michael Jackson as Speaker demonstration music in the Hi-Fi store, that's when I started looking elsewhere for music that would feed my soul and provide an antidote for the bad pop music that I was hearing at work on a regular basis. The early 1980s was when I discovered Ry Cooder, David Lindley and El Rayo X, Leo Kottke and other great guitarists with a more organic approach to music. In the mid-to-late eighties I discovered Richard Thompson and John Hiatt and that furthered my journey through music, a journey that continues to this day.
UD you could make a restoration of a beer can enjoyable. Thanks for your insight and comfy home style presentation
Thanks so much, Mike. How did you know the topic for our next video ??? :)
Re restoration of a beer can, of a sort..... my parents had a cottage on the shores of Long Island Sound that they bought when I was a baby. The water heater was semi-exposed in a little recessed vestibule by a narrow doorway entrance and there was no easy way to hide it and still have it accessible for draining or flushing at the beginning or end of the summer season. My mother disguised it by painting it to resemble a giant beer can, very realistically, although unfortunately I no longer remember what brand of beer can she copied or emulated when she painted the thing. It was pretty cool however, and she got a lot of positive comments on it. Unfortunately, my parents sold the cottage when I was about 20, because they thought that the crowd that my sister and I were running with during the summer were a "bad influence", and they wanted to protect my little sister from exposure to that sort of "riff-raff". As if such a thing was possible...... when the reality is that if one's personality leans toward running with "riff raff", then even if you live in Antarctica or on the Moon, you will find some riff-raff to run with! It wasn't like we really did anything to clean bad, we weren't slashing tires or stealing cars or breaking into empty cottages; after a day of fishing or swimming or water skiing and such, we were pretty tired, and we just kind of hung out on the beach and drank a few beers and maybe smoked some pot. Pretty normal American rite-of- passage stuff for teenagers during the 70's, really. By the way, we had PFD ( personal flotation device) boat cushions about the same color as the naugahyde seats in your Rat Rod!
GREAT LINE ! " I believe this oxidation is toxic, so I will be sure to lick my fingers after touching it"
.....and all my hair fell out the next day, but it was worth it :)
Enjoyed it!
Uncle D slips in some hysterical lines. If you aren’t paying attention, you’re missing the adult part of the show.
It seems a little reckless to start work on an amplifier without Jack sniff testing it first, please stay safe Uncle Doug.
You're right, Frank. He was off somewhere sniffing catnip and didn't want to help out. We've got to get him into rehab ;)
😂
@@UncleDoug better yet, legalize it!
@@UncleDoug Rehab is for quitters!!
WAY back circa 1980 while in college, I sang in a band in San Antonio. The band was two guitar players, bass, drummer, and me. One guitarist played a Mesa Boogie, the other played a Princeton. Both great amps. The fellow who played the Princeton had a professional cabinet maker build a new cabinet out of bird's eye maple. It was pretty much an exact replica of the Fender cabinet, in terms of size, angles, etc. It did not kill the sound at all, just was a really cool looking amp. Oh, and before he did the conversion, the tolex and speaker grill were shot (he bought it at a pawn shop,) so it was just a great improvement in the look.
But if I looked as good as that Princeton you are working on, at my age, I'd be one happy camper indeed! Thanks, and thumbs up!
You're welcome, Ken. Thanks for your interesting input.
Couldn't agree with you more about UPS packing. I can't count the number of times I've had issues with their packing/shipping service. Great discussion about the choice between replacing or rolling the dice and continuing with old caps...of course, only when they're still fully functional. Lots of great stuff here. Thanks Doug!
You're welcome, Leon.
I love your vids. you combine my two favorite things, cars and amps. I always learn something new here and appreciate your sense of humor. Your the man Uncle Doug.
Thanks, Jeff :)
I’m always glad to see that the solder flux is cleaned away after soldering. It stop further corrosion of the joint especially on steel chassis. Good work Uncle Doug!
I have recently noticed, in 1960's Fender amps, the result of not cleaning the flux.....brown corrosion. Thanks, Alex.
My Princeton I had back in the 60's had the best reverb of any amp I've ever had bar none. And, I have to say it has always been my favorite. Just a great amp. Thanks Doug for sharing.
You're welcome, Carl.
Agree 100%
As you know, Doug, I’m completely new at this. You’ve helped me loads, as I’ve just finished building my first 5F1 amp.
I had a weird oscillating noise at full volume, so did some testing and found I’d fried a couple of resistors.
Without your calm videos, I would probably have thrown it in a cupboard, but I’m now confident in changing components and “having a go”.
Thanks again.
Welcome, Andrew. It's great to hear that you are not only able to build your own 5F1, but can also diagnose problems and repair them. Keep up the good work !!!
As every one else here, I absolutely love your videos!
I would like to offer a bit of trivia. Long before motorcycle manufacturing, the Ducati family started the Società Scientifica Radio Brevetti Ducati in Bologna to produce vacuum tubes, condensers and other radio components. That Ducati capacitor you found was a piece of the famous Ducati history. On a sort of related topic... your diy hot rod muffler mod reminded me of how I gutted and refit my Ducati 996S stock mufflers into race worthy glass packs.
Your videos are always entertaining and inspiring. Take care.
Thanks, R52, for the nice comments and helpful info.
Uncle Doug's Custom Shop! When you need greatness to be perfected! Big difference on the reverb, well done!
Glad I watched this as I have a couple of vintage amps of my own, both completely original and functioning but as you say, it is a lottery!
This channel is so wholesome 🖤 I've been binging your content again, I do this every so often ...
We strive to maintain a family atmosphere, Mikka. Binge to your heart's content.
I just did the TremHound resistor mod to my '67 Princeton Reverb and it added that dimension of motion discomfort I've longed for! I always wondered my BFPRs didn't have the great Trem, even asked a tech who told me "that's just the way Princeton Reverb trem is". Not so! Thanks for this and all your informative and charming videos! Now I'll dig around for an NFB mod for the Mojo 5E3 kit I just built. Thank you Professeur!
You're quite welcome, ZZ. I'm glad the mods are working out for you :)
Wow! Kudos to the owner of that old Princeton! Pretty much museum quality, save maybe the footswitch....which I guess you'd call 'patina!' BTW, like you, I'm a fan of tremolo intensity and that one sounds really nice. Also, nice job on both the seat and the 'glas-pack' header baffle! Sounds really nice. :-)
Thanks, Norm :)
Doug, that new exhaust baffle sounds great! I LOVE the sound of a V8 gently huffing out of a pair of headers! I can't wait to hear it when accelerating. It's also great to see how comfortable KC is in her new home. Take care - Dave
Thanks, Dave. She has really adapted to her new home, and is eating like a little horse.
Uncle Doug, if you were a teacher of this stuff when I was in high school I would've attended two of your classes a day. You explain in a very easy to understand way. I love your videos.
Thanks so much, Rob. I would have loved to have motivated students like you in my classes when I was a math and science teacher.
What a way to start the day. Wake up to a new Uncle Doug video:-) Gonna be a good day for sure. Absolutely awesome work you are doing with that rat rod. Thank you again for all the help with that build of mine sir. I owe the fact that I successfully built an amp to you. Sure appreciate all your time and talent of teaching that you put into these videos.
Thanks so much, Kevin. It's great to hear that our videos helped you to build your own amp. Keep up the good work.
Nice baffle fab Uncle Doug.
Thanks, KB :)
I once received a pair of ADS 1290 speakers shipped UPS (among the finest speakers in the world, 1980s, weighing nearly 100 lbs each), and having no packing, not even bubble wrap, just 1/4” layer of cardboard against walnut veneer cabinets, and the world.
Miraculously only minor damage to one corner, and dented metal grill. It’s amazing how little thought people give to packing treasure. They were practically sent naked. UPS are heroes!
Indeed. I once received a very expensive antique steam engine that had simply been thrown into a box about 3 times larger than the engine, with a small handful of Styrofoam pellets tossed on top......and it arrived in perfect condition, against ALL odds.
That truly is an amazing looking amp for it being a '67. Great work on making that seat more Uncle Doug Friendly in the 1930 rat rod.
Thanks twice, Larry :)
Uncle Doug MVP of the internet 🎸🎶
Thanks, Eric :)
That's incredible Doug. My first impression, before we looked at it in detail, was that it was a brand new reissue. I wish we'd weathered the last 50+ years since 1967 that well 😀
Thanks so much, John. Glad you enjoyed it :)
When it first came out of the box i thought is was a reissue
Me too, A7.......too good to be true :)
Yes remarkable when you think that these were really considered student amplifiers and that most of them went out to some teenage wannabe that didnt take care of them too well. Think how many kids garage bands these things were at, kicked to the corner collecting dust all torn and tattered . Especially as the 80's came on and an old fender just wasnt cool, lil johnny wanted that 100 watter crate or cool heavy metal distortion peavy 100watt solid state buzz box.
Wow, really refreshing to hear someone else saying what I've been for years about UPS. I totally agree.
I wasn't born distrusting them, EE......I learned the hard way.
What a fabulous amp and great work Doug. Hard to believe that amp wasn’t kept in a sealed atmospheric case all these years.
Thanks, Charles. I agree :)
Fun watching you work, Doug. I admire your patience.
Thanks, John :)
Awesome, it doesn't get any better than a Princeton Reverb and Hot Rod tweaking video from Uncle Doug!
Thanks, Tom :)
Uncle Doug, that 'seat adjustment' is KILLER! Totally custom, and looks very professional.
The tremolo mod kicks bootay! HEFTY! HEFTY! HEEEF-TYYY!
Thanks so much, Dave......glad you liked it :)
Thank you Uncle Doug for sharing your wisdom with us!!!
You're welcome, F1. It's an honor to do so.
Hi Uncle Doug, I need you, we all need you and to see your wonderful family. You are part of my family, so the more we see you the happier we all are. Bless you!!!
Wow, thanks so much, F1. Likewise on the blessing :)
YES! Just what I needed today.
We're glad to deliver your Vitamin PR, Bill.
@Uncle Doug, You sure are young at heart and very active for being 71! I thought for sure you were late 50s / early 60s. Always a joy to watch your vids.
Thanks, Matt. In my feeble brain, I'm still in my mid-20's......a self-deception that works quite well in the absence of mirrors.
I have a 1978 Princeton Reverb head conversion and it is just marvelous. It will *not* do both clean and loud at the same time, but with the volume knob at 8 I feel like I could play for the Who.
Just don't start destroying speaker cabinets with your guitar headstock, Hub.
The amp and the slip in mufflers came out great and sound terrific!
Thanks, Jon.
Cleanest Fender Amp I have ever seen. Sure are enjoying the Princeton you brought back to life for me.
Thanks for the nice comment and very positive update, Bob :)
Finally getting to watch this video. Due to their length and the noisy nature of my room mates, I can't always sit and savor your videos when I want too. I got lucky tonight and have the
whole house to myself....so...(8-) And a great video it is. Both the amp portion and the rat rod portion. Glad things worked out well...even though Jack didn't pre sniff everything.
Thanks, Tom. I hope it was worth the wait :)
I just love princeton reverbs.. ugh that guy is a lucky amp owner
No kidding, CD. What a gem !!
My dad was a little older than you, and his brother is your age. You truly are perfectly aged to be Uncle! This Princeton is fantastic! I did the filter caps in my Valco Gretsch tremoverb, but when I searched, I had a lot of trouble finding the smaller diameter (1") cans. I ended up leaving it in place, and taking it out of circuit (replaced by the individual caps). When I did that, I also used your old rubber cement trick on the speaker cone surround. It really revived that old 8" Jensen and took the spikyness out of the tone. Thanks for another fun video! I really like the baffles you fab'ed up there for the rat rod!
Also I have to agree about UPS. They've lost and/or damaged more of my packages than USPS and FedEx combined. Lately I will actually pay more to not have things shipped by them. They always seem to find that 500 pound brick to set on my little box with a tubescreamer or something, and squish it
Thanks so much, Andy. I'm glad the speaker trick worked for you :)
I was glad to see another great video. Thanks Uncle Doug! I'm into solid state this week... Working on an old JVC cassette machine. The pinch roller is warped. I scraped it with a utility knife, it kind of helped.
You're welcome, Charles. Warped pinch rollers, just like dented turntable drive wheels, are no fun. Good luck.
It is this time of the week, chill and UD great videos. This should be a Netflix series. Thanks UD for the vid, keep a close eye in that catnip sniffing rascal.
PD this is the absolute best Princeton reverb ever seen on the internet: museum condition. Really amazing
Thanks so much, KV. I agree......it's a real gem. I enjoy sharing nice amps like this with you all.
You are amazing sir! I am humbled by your knowledge. Thank you for sharing .
You are very kind, Brock. Thanks :)
Gorgeous amp, sounds great! Your exhaust baffle sounds quite effective, at least at idle.
Thanks, Andrew. Yes, when you step on the gas, most of the sound ignores the baffle :)
From Leo: What a beautiful amplifier. Most of mine came from active gigging musicians and they are beat to death and have been rough repaired by whom ever they could find along the road. Half of the time is spent straightening up previous poor repairs. As always, great job, and good tip on the can capacitors.
Thanks, Barb :)
Leo Fender, Henry Ford and the Midas man would be proud.
What a great trio, Jim :)
Thanks for the quadcopter aerial view of the pristine-unmolested Princeton Reverb. We can now clearly see how factory assemblers crafted these gems.
It took months to master the flying skills necessary for such a close pass, Craig :)
Awesome to watch. One of ( if not The Best ) Small "Clean" Amp ever made. I have the 65 R.I. - and I must say I am pleasantly surprised on the Sound, Build Quality. Mine stays Clean way past 5 (which I love) as its Mega Loud and I use OCD pedal Overdrive. The Tone ( with the gorgeous Fender Reverb ) is on par with S.R.V. Riviera Paradise - which is my favorite Guitar Tone ever recorded. Love It.
Thanks, Michael :)
I too have had several issues with the function of Deoxit D5. I had the exact problem you had with the top coming off, and the spray ending up anywhere, but where it was intended. I sent the parent company an email, and they sent me a new can. It arrived in a box full of peanut styrofoam , in which I was totally bummed about. That can has worked fine, but I will likely not buy any more. My compliments to the owner of this amp to keep it in such pristine condition. Another fun and educational video. Thanks Uncle Doug \m/
You're welcome, Marshall.
The videos just keep getting better and better UD.
Very enjoyable. So true about the dodgy deoxit
aerosol. Lol
Thanks, DB4 :)
i like the way you interweave the rat rod and amp refurbishing into an interesting coherent whole !
Thanks, Sam. A change of pace from time to time helps to keep the audience focused.
Working on a tune by Buffalo Springfield "For What It's Worth" and notice my tremolo system on my Princeton RI sounds just like this '67 Princeton...I will make the change to get a better intensity to my RI...tks for the "tip". I remembered you doing this fix on the Princeton so had to "hunt" thru your videos and finally found it ! ! ! Hope y'all had a great Christmas and have a safe and happy New Year's Day/2020.......awaiting for you next video ;-))
That's one of my all-time favorite tunes, Tom. Good luck with your tremolo enhancement. I'm glad the video was helpful. Likewise on all the holiday good wishes.
I'm liking the more intense tremolo with the jumper you demoed. Reminds me of my '64 Tremolux's sound. It was quite distinct.
Thanks, TM. I really liked it too.
Amazing looking Princeton Reverb Uncle Doug!! It’s a true wonder that the amp arrived safe and sound.. I’ll never ship anything UPS.. mmm Mother-in-Law maybe( just kidding).. that amp is definitely a closet classic..didn’t even have the factory cover with it...50 years things can get separated..wow!! Great work once again!! Semper Fi
Thanks so much, Luth. It really is a gem.....and an honor to work on.
Hey uncle Doug, another great video. The hot rod is look'n and sound'n great!
Thanks twice, John.
Thanks Uncle Doug! I’m also loving the El Paso Tube amps channel, you guys seem to have a lot of ampaholics in El Paso
Actually there aren't many, but we tend to post a lot of videos :)
Well done once again! Also, good to see the cats are doing well!
Thanks, Erich.
Doug you are the man! I love every one of your videos beginning to end. Thank you so much for the resource you provide us FOR FREE! I owe you big time!

You're quite welcome, Chris. We appreciate your donation and hope you continue to enjoy our videos.
Uncle Doug 👍
I have never seen anything this well preserved. I would be afraid to work on it. I look forward to hearing it. What a surprise you found for us to see and hear. What a wonder.
I'm glad you like it, TJ.
@@UncleDoug Doug, that amp looks almost as good as one of your jackets.
I'm not sure if that is flattering to the amp, TJ ;)
@@UncleDoug Ha! Good looks, good tone, and good fun. Win!
Amen, brother :)
20 years old when this amp was built? Gosh I'm just about 20 now. I wonder what I should be remembering from my first 20 years.
Remember to subscribe to our channel, LH.
Another great restoration Uncle Doug!!
Thanks, BigJoe :)
SO CLEAN AND NEW LOOKING, THAT IS AMAZING
Yes, indeed :)
I slowed the tremolo speed on my '65 PR and increased the intensity. Now, the tremolo is useful.
Thanks for sharing, J1. We're glad the modification was useful.
So clean, Uncle D.
Thanks, LD :)
You are the coolest uncle ever.. thanks for sharing! love all your projects.
Thanks so much, Frans.
Just recently aquired a brand new 64 princeton reverb handwired.. it is glorious
Is it an original '64 PR or a modern hand-wired reissue? Either way, I'm sure it must be wonderful.
@@UncleDoug a re issue... thats the joy . I play in a blues band with far better musicians than I.
I do have moments of great joy and indeed the band all agree the tone i have is just stellar. . I will likely be long gone home by the time it needs service and if im a good steward it (and a few other jems ) will bless some special person and all who listen for years to come
.
@@UncleDoug and may i say watching ans listening to you share the wealth of information and love for things such as this really does inspire me .. Thank you so very much.. i miss Rusty. The Cats are a great quality assurance team as well.
Ripping good stuff !! I was nine in '67, Canada's centennial year. My older brothers started their first band in '68.
Thanks, Mr. CC. Those were the days !!
Great amp, great car, and what a beautiful cat you added to your collection:)
Thanks three times, Murrat. We all really appreciate it :)
Outstanding and so very informative. Thank you sir!
You're welcome, John.
What a pleasure to watch. Thanks!
You're welcome, MM :)
wow! that is super clean....looks brand spanking new!!!
Yep......it's a real gem :)
The quality and condition of this fine instrument pairs nicely with Jack's discerning pallet when assessing a rare bee's wax transformer or a 20 y/o single malt dog biscuit. Good stuff!
Jack agrees, Trebor. He put on his silk smoking jacket and was enjoying a snifter of fine brandy during the repair.
A very nice ampere, that owner really cared for it over the years. It is always so much nicer working on something that has been cared for, then something that has been stored in a garage or barn where the rodents and elements have their way with the device.
Nice additions to the "Rat Rod" as well. it sounds and looks nice!
Oh yes and Casey looks quite comfortable and content on that cousin!
Yeah that amp is obviously a bedroom arena amp!
Thanks, Guys. I did miss not having to scrape out 4" of urine-soaked rat's nest, but, as Mick says, you can't always get what you want :)
Very clean amp UD, must have a pampered life (like Jack). I am put off more by the tubes (some nice RCA's or Sylvania's for that vintage amp), than the replacement of the can capacitor. I wouldn't have changed it, though understand why the owner did. Big thumbs up on the Tremolo mod, what a difference. The Rat Rod is coming along nicely, I thought the grill that came on it tacky (positive someone will buy it though), and can only imagine the noise before the inserts you made. Great job A+.
Thanks for all the great comments, Tom.
Doug, I use the DeOxit also and when it gets plugged up, I turn the can upside & fire a shot or two. That usually unclog the nozzle. This works with spray paint too
Thanks for the tip, KV :)
Another great video! FYI, there was a stock Ducati capacitor in my ‘67 Deluxe Reverb, so Fender was using that brand in 1967.
Thanks for your nice, informative comments, Jeremy.
Great little Tremolo enhancement trick...
Glad you liked it PM :)
@@UncleDoug Nice handwork on the UD RatRod special exhaust mod as well. It's ashamed I'm still not working at the last co. I got laid off from, I would have mode some vinyl badges and insignia for you to help trick it out. We did everything from from storefront window insignia to wraps, to very large precision signage, not to mention the metal work... Hopefully, I'll find something soon. The east coast is a hard town in the mfg business. Management leaves a lot to be desired... We're, journeyman machinist, just looked at as "tools" to be discarded after need/use like brick-layers, etc... :( Such is life. We all have to answer in the end and there's no where to hide for anyone when that day comes... KUTGW! Lovin' your stuff!
Dude. You are priceless. Happy July 4th to you and yours! 🇨🇦❤️
Thanks, Anthony. Same to you all :)
Uncle Doug Is Awesome.
You are too kind, BB.....but thanks ;)
Great vid!
Thanks Uncle Doug!
You're welcome, Jason.
Hi Doug -- I have personally found that those bias vary fender trems sound best when the power tubes are biased on the cold side -- best wishes, Ben
I biased the PR rather hot to suit it's predicted use, Ben......moderate volume with early breakup. Thanks !!
agreed otherwise the trem runs out of room when no more bias is left to drop out. but his mod seems to offset this a bit
Thanks Doug! That is a beautiful amp!! I have my old-style Weller D550 240/325 soldering iron with homemade 10 gauge copper wire tips for those tough jobs.
Thanks, Robert. You really need some heat to solder on a chassis.
Yes sir!
Uncle Doug. Can’t begin to tell you how much I enjoy your channel. The most worthwhile channel on UA-cam for me. Thanks again. If I might indulge you for two questions. I’ve got this identical 67 Princeton reverb. I’ve got an amp tech here in Los Angeles that has worked on this amp a few times. I believe it was getting a high pitch squeal that he repaired before. As I recall it was just a matter of checking some cold sounder joints I believe. In any case I was interested in trying another speaker to see if I liked the tone better. I had an original Jensen P10r I believe. I have a P10q plus I purchased a speaker from Warehouse Guitar Speakers ( on the recommendation of an excellent player). My thinking was I’d remove the baffle and change the speaker and reinstall. Seems simple enough but when I pulled the baffle i found the particle board original was disintegrating so badly that I decided to make a new baffle and install that to demo my new speaker. I used Baltic birch I purchased from Home Depot 1/2”. Once I did that the amp displayed a very erratic distortion that seem to get worse as as it heated it up and so I just turned it off for good measure. I found a local repair guy and took the amp to him and after an hour‘s conversation about Amp Repair which I didn’t need to hear especially since I don’t think he was as competent as he wanted me to believe he was, he told me all it needed was new tubes. He tapped the tubes with a wood stick as is commonly done. He pulled one of the output tubes which was super hot and showed me that they were both operating independent of each other. He put in a new pair of tubes that he had and immediately it played better. Problem solved but...I still have concerns. My question is being an old Amp guy I’m not sure that you can just install new power tubes without checking the bias. I was going to engage you to steer me in the proper direction here. Again appreciate any help and advice you could offer. Perhaps I should just send it to you and let you rehab now because then I know it would be done right. You do such great work and I’ve got tons of old fender amps.Thanks again uncle Doug.
In fixed bias amps, you HAVE to re-bias after every output tube change, David. This is not that difficult to do if you study videos currently posted on YT. It's best to develop skills and become more independent, to avoid problems like the one you described. See if you can't straighten this out yourself.......shipping for repair can get expensive.
Thanks Uncle Doug. Much appreciated. I’ll do as you suggest. I’m on it. Thanks again.
I don't care who the carrier is; I never let anyone else pack my stuff. I have personally had more problems with FedEx. For the money they must charge to pack stuff you could buy double wall boxes and the best bubble wrap and foam padding. Beautiful amp.
Thanks, Ed. I agree. Trusting others to pack for you is like trusting the Hell's Angels to babysit your teenage daughter......odds are it won't end well.
@@UncleDoug UPS
USELESS

Love your vids!! I'm on board with you Doug!
That's great news, MS. Welcome !!!
Beautiful Blackface ! Cool car ! great video !
Thanks, Jason :)
I found your next project. The Morley Oil Can Wah. Just a wild effect.
This Princeton is nice, my favorite Fender amps. Wish I could get a the new 62 Brownface Princeton reissue Fender just came out with.
All the oil can devices offer wonderful effects, John. Please see my video on the TelRay Organ Tone.
My UPS woes, I purchased a vintage 68 era mustang and twin reverb that had spent their entire life together in California. I'm in SC. The seller paid to have UPS pack. They put the mustang in a wardrobe box. It took a hit so hard that the headstock punched through the side of the case. Luckily the neck is ok. The twin was placed in the middle of a large square box. Because the 50 lb center of gravity was flopping around you couldn't pick up the box. I witnessed the driver roll the box with vintage twin out of the truck. When I unboxed it the case of course was smashed, cracked and lose. One spot was hit so hard that the wood splintered. I took it apart, reglued it all the best I could. I had to cut and peel back the tolex to get glue in and reinforced with screws. glued the tolex back down that is worse for wear. I had to rebuild the splintered corner with epoxy wood compound. Luckily the amp worked. But yeah packing yourself is much better. Also I found the competitive rates purchasing shipping on line is better than what they will give you in the store. Thanks for videos.
Thanks for sharing, KS. Nothing you said surprises me in the least.....and the inaccuracy of their web site rates is really annoying (to say the least).
Very cool...I just paid off a 67' Princeton Reverb made in April as well, but mine came with a Jensen C10N .....It took me forever to get one for a few reasons. Worked my ass off plastering walls for weeks , but it's worth it!!!! They are hard to come by!!!
It sounds like you worked hard and ended up with a great reward, Ian. That's the way it should be :)
@@UncleDoug thanks man!
@@iansnyder274My pleasure, Ian. I like it when people work for the things they want.
@@UncleDoug Yep, there's a lot to be learned and gained for sure!
I'm up in Canada here, Doug, and my rotten kid (son) has a mid-60s Fender "Bassman" amp that could use some work. To be sure that the unit gets safely to your shop, and not abused by UPS, the wife and I could hand deliver it to TX about next November and stay with you and the crew at your home until you have the unit refurbed .... say about April 1st. We are in our 70s, love cats and we don't eat much :0)
Will you be bringing your painting gear???
@@raindogred this is hilarious
@@Starcrunch72 Remember we don't make mistakes when playing with high voltage tube amps..just happy little accidents lol
Your offer couldn't come at a better time, Bob. We plan to re-do our roof, floors, walls, bathrooms, and kitchen about that time, so you and the wife can help us. Naturally we'll be camping out in the back yard, scavenging for food, and bathing in an irrigation canal......but heck, it'll be an "adventure".

10 dislikes? WTF! Anyway, have you seen old radio nuts who will re-stuff can caps to look original inside and out? I even saw a guy so hopped up on originality, black coffee, and big band Jazz that he even re-stuffed and beeswax-dipped wax caps! Wonderful vid as always, I'm in love. That amp slays the rest I've ever seen. Had a guy over the other night with a blackface bassman that was almost as good, but still, this one tops them all. I enjoy the hot rod sidelines. I'm sure I'll be doing the same thing with my vintage Toyota 4x4 pickup when I get to your vintage.
I agree about the dislikes, JT. It's hard to believe that ten genetically-deficient, slobbering lunatics could actually operate computers, let alone be able to press the thumbs-down with their prehensile tails :) Thanks for the nice comments.
I love the amp... Wow. I also love the rat rod interludes.
Thanks, GG :)
Always a pleasure to listen to you and watch you work. Only tiny issue is we could have heard that rat rod running a little more, Perhaps do a segment with it being driven? We dont get to hear many in The Czech Republic
Thanks, Mr. G. I do intend to have longer exhaust demos. I was running late for a car show in the final scene and had to get going quickly.
love it. your a multi talanted guy. love the amps and the hot rods. id watch both channals if there were seperated. as always thanks for your time. being a stealth guy cool.
Thanks, DH :)
Nice job Doug. It would be cool to use that unused ground switch to create alternate tremolo sound.. 500K in and out. What a beauty that amp is.... truly. Ron
Thanks, Ron. That's an interesting idea.....but for Tremolo hounds like us, the switch would always be "on" :)
Great work on the amp! Was disappointed that you didn't give the rat rod a rev or two! Sounded healthy though! Thanks for the video!
I couldn't rev it from outside the car, MC......but I'll find a way in future videos. Maybe we'll go for a ride, if I can get someone to hold the camera. My wife refuses to get in it.
Shame on her! Thats an awesome looking car! I love the rat rod style, so I am biased. Love see both in your videos. Also the job on the seats is awesome.
love the amp but you got me on mufflers this time ... I learned a lot from guys who made exhaust systems for motorcycles years ago and it worked pretty good for me. I usually wrapped the baffle insert with stainless steel window screen to keep the fiberglass from blowing out through the holes so fast. With megaphone pipes it wasn't as bad as a straight wall muffler but it helped a lot to wrap the fiberglass with masking tape before pushing the insert into the muffler. That way it didn't bunch all up at the end and allowed the fiberglass to fill the whole muffler. The tape will smoke and smell for a bit but it burns off in half an hour or so. Gotta love mufflers :)
Yeah this is good advice^.. also id buy actual exhaust packing for $15 and probably add some steel wool with it.
Thanks for the advice, guys. I'll keep it in mind for the future.
@@UncleDoug I need to listen to what you have to teach about amplifiers and really learn it so I can put some of this stuff together laying around here.
Beautiful Fender reverb!
Thanks, DS.
DIY glasspacks ! Gotta love those :)
Yes, indeed. They do take some of the really awful "bite" out of the exhaust sound.
