1967 Fender Bandmaster: FINALLY.....A Cooperative Patient
ฝัง
- เผยแพร่เมื่อ 28 ส.ค. 2024
- After a long run of nightmarish repair challenges, I finally encounter an amp that responds well to my efforts: a beautiful, completely original 1967 Fender Bandmaster. After routine replacement of electrolytic caps and several carbon comp resistors, rewiring of the primary circuit, tremolo and bias supply tune ups, and output tube biasing, it sounds like a million bucks. No previous botching, continuous disasters, failing tubes and transformers, inexplicable hums and crackles, smoke or explosions......it simply emerges from surgery in perfect shape, ready for many more years of service to its lucky owner.
In addition, we will visit Jack and KC during their "cat naps", and take a ride in a 1934 Ford pickup with newly installed tunnel ram and dual Holley carbs.

Nice to see you back
Fender Vibrato and Paul Westerberg is pure bliss. Just like cruising in a VW 36hp Low Light Ghia.
Life is good :)
Your the Man, all of us gear people love your work
Thanks, Steve :)
Thanks for the ride in the purple monster uncle Doug I needed to get out a bit What a machine
Fender amps are incredibly tough ... And this one is beautiful.
Agreed....twice :) Thanks, TT.
Wow Uncle Doug. Valve amps and Hot Rods.
Looks like your'e living the dream. How cool.
UNCLE DOUG!!! What a treat!
Thanks, Mike :)
Thank You and stay safe.
You're welcome, Michael. You too.
I've never been much of a fan of TH-cam'sters that include their pets in the video. But, in your case Uncle Doug, I've always been more accepting and never known quite why. I think today I finally have figured it out. I think Jack is much more relaxed and entirely more helpful than most pets. Other pets always seem to talk too much. But, Jack seems to know when it's best to hold his tongue and when it's time to express his humble opinion with less words and more action!
I tip my hat to you, Sir. Not only for having raised a fine companion; but, also for providing another thorough, instructive and easy to follow video!
Thank you for the service you provide mankind.
Thanks from both of us, Richard. I agree that other people's kids and pets are generally a nuisance and distraction.....but Jack was raised to be "seen and not heard", and thus is a trusted confidante :)
That's so evident! LOL!!
Thank you Doug. I have 2 Fender Bandmaster Heads that more than like need Recapping, It's amazing how much Techs charge for shop time on Tube Amps, Seems if they'd lower Service charges it'd equate to more business Thank you Uncle Doug. I love the sound of tube Amps.
You're welcome, Heen. Keep watching and maybe you'll be ready to perform your own basic maintenance.
What a beautiful amplifier! Thank you for sharing!
The pleasure was ours, KW.
Thanks for all you do. You have helped me out so much with all your videos . Please don't stop. Keep on truckin.
Will do, Joseph.
Hooray! Just when I was wondering if everything was ok over there.
We're doing just fine, Daniel. Thanks for your concern :)
I was just given a free AB763 Bandmaster head this past Monday. It had been left out in the shed for over 30 years, and there was enough dirt on it to grow potatoes! It's the early silverface with the little aluminum trim around the grill cloth. The tube chart says AB763, and sure enough, it checks out with the schematic to a "T" . No CBS silliness anywhere! thanks to your excellent presentation on your video, I was able to get this thing running, and blow out all of the gremlins (noise, crackling, hum, etc) in record time. For about $15 worth of parts and a few hours time, I am now the owner of a righteous Bandmaster that sounds like God shouting from the mountain top! Your advice and expertise are far advanced from what I know, and I must thank you a thousand times. Much respect and admiration to you sir!
It's great to hear that you put the video knowledge to good use, JP. Congratulations on a successful restoration :)
@@UncleDoug Thank you again, and I have to say that you had a hand in the process. My new old Bandmaster rocks the house.
we all love uncle doug
Thanks, Ian. Jack & I are flattered :)
The sound of this one ended up Superb. great vid UD, thanks!
Glad you liked it, K. Thanks !!
Uncle Doug and a cuppa great way to start the day! thanks again for imparting more pearls of wisdom to the masses!
What an absolutely sweet sounding amp. You did it justice, and it honored us with its Presence :)
Thanks so much, Jules. That was definitely our goal :)
Glad to hear you're doing well!
Thank you! Same for you, I hope.
Allways a treat for a new video from Uncle Doug!!! The Ratrod is very nice !!! glad you are healthy and doing well ,awesome amp thankgod it made it with no damage
Thanks so much, Joe :)
Glad you are keeping well and thanks for another interesting repair of a marvellous vintage Fender.
Stay well!
Thanks, you too!
Very happy and relieved to see another video from you, UD! Hope all is well with you and yours!!
Thanks, Greg. Never better.
Wow, she was a real beauty on the inside.
Yes, indeed :)
Cactus and car are both beautiful !!
Thanks, Bert :)
Spirits lifted again with a new Uncle Doug video. My favorite type of oxygen.
Thanks Uncle Doug! I always learn something good.
That's our goal, Shaun.
I'm re-watching this video after recently buying a 1967 Deluxe Reverb. I really appreciate your thorough explanation of how the screen resistors and grid stoppers function. My brand-new to me amp had the v8 power tube fail in the first half hour of playing it, frying something inside and releasing gray smoke! At first, I was mortified that I had somehow killed the power transformer, until I opened up the chassis and saw the roasted screen resistor (which was already pretty dark). I remembered that you had talked about these before so I went back to find this video.
After watching this video explanation again, I know understand much better what happened. Thanks!
A burned screen resistor generally indicates a short within the tube, Wes. Replace the screen resistor and the tube.....and see if the problem doesn't disappear.
Thanks for the drive. I could just hear Marty Robbins singing out loud and clear along the way.
Thanks for joining Marty and me, Jeff :)
The amp sounds great uncle doug
Thanks, Brett :)
@@UncleDoug you're welcome
I miss Texas every time you take us for a drive. Beautiful pickup truck!
This video came to my attention at the perfect time. I just bought a 66 Bandmaster online and am expecting to replace caps and so forth. I don't use vibrato so I usually ignore it but your walk through on this circuit has enticed me to check it on the new amp when it arrives.
Thank you for your excellent videos!
You're quite welcome, Thomas. Glad you enjoyed the video.
Your videos are the best content one can find on youtube. Greetings from Argentina.
Thanks, Nixo :)
Warning! Watching UD and sipping a drink can be both hilarious and hazardous 🤣
Also for anyone sitting in front of you :)
Uncle Doug 😆
Keyboard-killing coffee spray is a real danger.
A really sweet sound. Thanks, Jack & Ollie. (I don't get Unc's tremolo thing, but, hey. Keep the ol' fella amused, guys, the world's a better place...)
Thanks, Bill :)
It's good that you're ok. We were worried sick.
I'm sorry, Jeff, and I really appreciate your concern.
Got one just like that that needs your attention Uncle Doug
I hope it's as easy to repair, WE.
I like your chassis stand rig. Tall and adjustable its cool.
It was a gift from a generous viewer, Charles.
Yeah, that thing is really clever.
Always a treat to see a new Uncle Doug video - hope lockdown hasen't been too much of a trial for you & your loved ones.
Thanks, Spud. It's actually not much of a change. I generally spend several hours in the workshop daily and then take a spin in a hot rod for some fresh air.......pre and post quarantine ;)
Hi Doug. Thank you
Anther great video,'Uncle Doug'! I always' learn something from your videos',every time that I watch one!Glad you are doing well!Enjoyed the 'hot-rod' ride!Take Care!
Thanks for joining us, Charles :)
Great to see you're not afraid to put metal film resistors into vintage amps. I was just working on on a custom unit full of carbon comp resistors made in China. Every single resistor was out of tolerance by a long shot. Garbage. Your ride has that sound. Back in the day Thrush muffler ads used to call it "The Mellow GT Sound" Good times.
Thanks, John. I prefer them in the power supply and as grid and screen resistors. Although the '34 has exhaust pipes that go under the body (from the headers), they are simply straight pipes......no mufflers at all :)
I was worried about you Uncle Doug , glad you are all ok there . Love the Truck . It was funny you said damn it and a cop rolled up on the other side of the high way at the light. I know you said that about the light changing. Was funny.
Thanks. The camera doesn't miss anything, Marcus ;)
Your guitar playing has really come along nicely.
All praise goes to Jack & Ollie ;)
@@UncleDoug , the cats play better than I do!
I was just thinking the same thing.
@@billklement2492 Think how I feel when they outplay me too ;)
Another excellent Video Uncle Doug!!
Thanks, Big Joe.
Happy 74th I will be 64
Later in 2021. I hope you live long say 94
And still able to work on hotrods and amps
We out hear in ampaholic UTubeland
Like you and your work
DBJT
Thanks so much, Dwight :)
Doy gracias a Dios que esta bien de su salud. Muy buen video, me diverti mucho con los gatos y con el paseo en la camioneta, ademas de la actualización del Fender 1967. Saludos desde Argentina y que siga bien de salud y buen humor, Dios le Bendiga en todo momento!!. Angel Gabriel Gras.
Apreciamos tus amables palabras, Angel. Los gatos y yo te deseamos la mejor salud, felicidad ... y éxito en todos tus proyectos.
I used to play through the exact same type of amp in the late 70s. The fuse holder used to get bumped and the end would fall off into the back of the cabinet. Beginning of the night I would reach around with bass in one hand to turn it on and my fingers would brush by the live fuse poking out the back. Zapped me many times!
You're lucky you weren't touching the bass strings at the same time, Dean. Glad you survived :)
Nice to have you back Doug. Glad to hear you're in good health. F&T caps are awesome. Can't go wrong there. Rubio Golds are nice also (especially on tone, from my experience). I agree, too much money for the Other Ones (Sp.....).
Thanks, Bert. I agree :)
Sorry bout the bite brother.
Tks for another amazing video with two of my favorite stuff....valve amps and engines...that engine sound it's just a dream...stay safe!
Great video as always!
Glad you enjoyed it, Dave.
Nice clean work!
That amp sound amazing! Great video as always ,thanks for all your videos ,i'm fixing an old italian tube amp and i've learned a lot just watching you work! 👍🏻
Great to hear, A81. Good luck with your project.
@@UncleDoug thank you ! Hopefully i will finish it soon👍🏻
Another great one... thanks. I’ll second the advice on equipment, I’ve worked in the electronics industry for several decades and use only Fluke on the job because my livelihood depends on reliability year after year without question, but having compared even the most inexpensive meters available I found they are just as accurate. The only real difference is they aren’t quite as fast, which is not important in most situations. Having two $20 meters will get you further along than one $500 Fluke most days. I will say Fluke is good value though, I’ve had my Fluke 87 for probably 30 years and it’s never once let me down and still going strong even after taking a beating everyday for all those years.
Thanks for sharing your knowledgeable input with us on this matter, Robert.
Glad to hear your all OK, sweet amp, sweet ride, cool dude.
Thanks, James.
That truck looks & sounds fantastic! The amp isn’t bad either. ☺️ Nice part of the US to take a drive in too…been fortunate to spend some time in the general area.
Thanks, David. Yes, there are lots of open spaces to "stretch your legs" in a hot rod :)
You are a great and genorus man for sharing your knowledge we appreciate it very much
Thanks Uncle Doug, that was great as usual: love the test tunes.
wow. to pack such a jem so poorly.. thank god it arrived fine. I appreciate the new video Uncle Doug!
You're welcome, KG :)
Uncle Doug is the hickok45 of tube amps.
Good video partner.
High praise indeed, Smithii. Thanks :)
Thank you for the trip with your car 👍very nice 👌I enjoy your videos. Greetings to the Cats!
Thanks for watching!
My favorite channel is back with another fantastic video. So glad you are doing ok.
Thank you so much!
Glad your back great video love the hot rod !!!!!!!!!!!!!!!!!!!!!!!
Thanks 👍
Nice work on the amp, and a great hot rod. Good to hear from you again.
Thanks, Hack.
That was a really great show.. I've missed your content. Glad your all well..
Thanks, Kerry. You too, I hope.
The BF Bandmaster and it's combo version The Pro ab763 are my faves. Such a versatile amp
Keen to watch this one
UD can magically make new parts appear in an instant. Guess that's gotta come in handy!
Indeed. Now if I could only make that happen with my stimulus check ;)
Oh happy new year! I was wondering how you were, thanks for everything. from France
Hey Uncle Doug, great to see new stuff from you! I wanna thank you for your informative and entertaining videos. Thank to you I gathered the courage and the knowledge needed to build my first amp, which brought me great joy and pride.
Keep up the great work!
That's great news, Giovanni. We're glad to hear that your first project went well.
@@UncleDoug Cheers!
Glad to hear that you're feeling well. I always love to see a Bandmaster. Great playing at the end. Thanks Uncle Doug.
Thanks, Rohan.......glad you enjoyed it.
Love that truck! Keep adding the hot rod stuff please 👍
Thanks, Jeb. Will do :)
I love your adjustable wooden test stand! Another great video
Doug, your playing gets better almost by the day!
Thanks, Fabio. It's all due to the gracious assistance of Ollie & Jack.
At 13:25 if only shipping was that fast! LOL Great repair to make like new once again!🔊🎵🎵🎵
They do offer good service, HM. Thanks !!
Hi UD, great job and... a very wise idea to bias at 60% . IMHO 1967 was the golden year for the Fender amps.
Amp sounds very good. Woaaww that truck ! At the first corner is was like a 747 waiting for lift off :-) Keep healthy Sir, Joseph ( Spain )
Thanks, Jose. I tend to be conservative with bias. It feels like a 747 once launched ;)
Cool amp Doug you do nice work!and thanks for the ride!Cheers
The Bandmaster looks so pristine, I thought it was a reissue.
It was a nice one, R5.
Good to see you're back and fine. I have been thinking about you lately, and honestly, I was getting a little concerned.
Thanks, Berre. Never fear. Like death and taxes, we're not going away anytime soon :)
Great video Doug, thanks for this one. lots of memories as I built my first amp from a Xerox copy of a Bandmaster schematic I got from a friends Dad who was a TV repairman back in 1968. Bent my own chassis in metal work at school and bought Fender transformers from the Fender distributor in Canada which was local to me. I remember I had to wait to save the money to buy the neon-resistor for the tremolo circuit it was one of the most expense parts in the build at the time. I think you should of pointed out to your viewers that you can date the transformers by the mfg. date code 606 is Schumacher which all three were sourced from the 606-630 would be 30th week of 1966. The 606-6-38 the 38th week of 1966 and the output transformer 606-6-42 is the 42nd week of 1966. This would give great weight that all the transformers are originak to the amp. Again an other great job and hope to see more tube amp videos in the future.
Thanks for your very nice comments and information, Bill.
Im glad youre back and well. Neat Job on the Amp and what a nice pickup:).
Thanks, Heinrich :)
Your truck! I want! First vehicle I ever rode in, was a 1944 or '45 Ford truck, in 1947. Saw one JUST like it a couple years ago, with no improvements to it at all ... holes, rust, same interior, no improvements ... I loved that thing.
i use to think Rusty spent to much time hanging around the garage with those rusty old trucks instead of practicing his guitar.but now I think Jack and Ollie have been coming up with some pretty enjoyable music.....thanks .....plus I hope you dont mind if I am using some of your material in some of my more humorous narratives
No problem, Phil. We probably stole it from someone else ;)
Welcome back Doug. I missed watching your videos. Can't wait for the next one.
Welcome back and certainly missed your informative videos.
That Engine is some of the best music I've heard lately.
Thanks Uncle!
Glad you liked it, Juan.
Kudos, "Uncle Doug". Your videos are excellent and I've learned a lot over the years. I can't thank you enough for generously sharing your knowledge! Keep up the excellent work!
The owner/shipper of this amp has NO IDEA how fortunate he was that this unit wasn't totally destroyed during the shipping process! Expect your parcel to be handled in violent ways (dropped, thrown, shaken, bounced around for hours during transit, etc). It should take an amateur "packer" about an hour to properly prepare something like this vintage "Bandmaster" for a trouble/damage free trip in the hands of the shipping apes. Double boxed, for sure, and padding inside BOTH boxes.
Realize your package may be sideways, upside down, jammed between other parcels, etc. for long periods of time and transit.
Also a good idea to ALWAYS remove those beautiful vintage knobs for shipping. They crack easily and if not packed properly (like this example) some, or all could be broken in transit as well as the pot shafts getting bent or broken.
After you've finished packaging your parcel, you should pick it up and shake it pretty hard (up and down / side to side). There should be no movement felt from the contents inside.
Finally, as shown on "Uncle Doug's " work bench, the amp is out of its cabinet on his "test stand". With the tubes and knobs removed, this is an EXCELLENT way to ship the unit. It can be rolled up in bubble wrap and be very secure. Remember, the shop doesn't need the cabinet for anything and you'll actually save them some time from having to remove and reinstall it. You might even save a little on shipping cost due to the reduced weight!
Thanks for your detailed explanation of the proper preparation for shipping. The other "downside" to inadequate packaging is that, as a result, I have to spend several hours scrounging up the proper two boxes for return shipping and then packing the amp......which is a task that I may begin charging extra to perform.
it is good to hear you are ok, Uncle Doug!
very addicted watch your video, even it's to long to watching =)
YES! Thanks Uncle Doug! Now I feel better! Glad you are safe and sound!
We appreciate your concern, DK.
Love the video! Both the Fender and the fenderless sound amazing!! Cheers!
Thanks twice, Rick.
With all those indulged felines to attend to I'm glad you still have time to diagnose Fender problems UG - those cats seem to be quite demanding of your time. I'm pleased they're still willing to test your repairs once completed though! I enjoyed the ride at the very end. I always have to drive, but not in such style I'll admit. Great vid UD thank you. Hope you're doing well at this time.
Thanks so much, Guy. We appreciate the nice comments and are doing quite well. Hopefully, you are too :)
Hey UD... Can't wait to see the work done on the hotrod. I'm building my first 5F1 amp/head cab with a 12" speaker cab. I need to revisit your cabinet building video for the finger joint review.
Good luck with your project, James. I hope the video is helpful.
Nice to hear from you Doug! a nice ride after another fine job!
Geez uncle Doug you have a fun life. Fixing great amps and driving classics across the Rio Grande. You are blessed, thanks for your great video uploads.
Thanks, Keith. The best part is hearing from all our great viewers :)
There's something in the sound of that engine that just says, "Floor it."
Balanced by the voice in my head that says, "Stay out of jail" :)
@@UncleDoug Sadly, too true.
@@UncleDoug, the cops are afraid of pulling you out her in MD. I have to stay right to not be run over!
Hey Doug, I'm finally a round to it. Thanks for video. BTW, I laughed out loud at the orange hand towels on your amp service rack. I grew up with the same set, can't forget what I wiped my hands on for decades.
Our pleasure, Craig. Watch our latest video to see your volt-amp monitor in action :)
@@UncleDoug Spoiler! I haven't watched the Magnatone rework video yet. Glad it help out in your tone restore quest.
The V8 is music to my ears ♫
43:03
Uncle Doug, I feel ya. I pass through the intersection of Damnit and You SOB Dr. twice a day..
Thanks for the meter tip. I have recently started looking at Mastech to replace my sluggish Amprobe and the reviews are very positive for a DMM in that price range.
You're welcome, Randy. I really think you'll be pleased with the Mastech.
For a novice electronics hobbyist, these videos are awesome. Glad to hear you are doing well and what a sweet 1967 Bandmaster! Thanks for sharing.
It was our pleasure, Adam. Thanks for your very nice comments.
this thing just survived the greatest threat ever to its existence; demand that this owner buy a road case & send it for the return & all future moves of the amp - it's worth thousands surely
It was quite lucky to survive......and from my experience, such luck rarely repeats itself.
One of the best amps Fender made. I owned a '68 SF w/ the AB763 circuit and it was a jewel but had some issues. Sold it to buy my wife a Christmas present. Things we do for love. :)
Amen, Joseph ;)
