  • In this vid, we'll overview how to adjust the output tube bias on most vintage Fender guitar amps and look at some of the common cleaning procedures for when you have static and crackling noises. We'll use this mid 60s Santa Ana labeled Band-Master Head to do it. At the end, we'll demonstrate the tone in our usual fashion.
    TOOLS you'll need:

      @@1NicholasInSeattle Right now I think reverbDOTcom is the best place to sell amps, and Craigslist is still good. BF & SF Bandmasters usually go from $500 to 1,000 depending on year and whether or not they're a reverb unit. Or at least they did. They've been edging up in price the past couple of years. If it's in really good shape, you might get a few hundred more.

    Great video, Brad. I have one of these from June '66. The transformers in this one were made in '66 but this amp was put together in the 15th week (April) of '67. See the QD date stamp on the tube chart at 4:33 and the assembler/inspector stamps (xx#1567) between the preamp tubes at 6:30 and inside the chassis at 10:20. That being said, you did wonders for this amp by cleaning the jacks & pots and warming up the bias. And for his own sake I'm glad the owner agreed to the AC wiring fix!

    Great tip on lifting up the strap for bolt removal!
    REGARDING PUTTING A FENDER AMP HEAD CHASSIS BACK INTO THE WOODEN CABINET:
    That transformer side strap bolt is real tough to get the nut back onto. Try this: wrap up a good length of transparent tape, sticky side out, so that you make a circle. Stick one side of the circle to your longest or most usable finger, stick the nut to that tape, and stick it on the bottom of that strap bolt and just hold it there. Turn the bolt, not the nut. Works like a champ.
    And BTW: You can pop off a Strat knob by using two very small flathead screwdrivers under the knob, opposite sides, going opposite directions ... inch the knob up slowly.
    You can use a long, narrow flathead screwdriver that will fit inside the loop of a tremOlo spring, holding the hook into the bridge block; stretch the spring, placing the flathead screwdriver against the far side of the receiving bracket hook, and pry the loop down on to it. Works like a champ, but of course, be careful. And those Raw Vintage springs make your Strats easier to play (you will most likely ALSO, lose the spring reverb chimes). You might note flexibility improvement right away; but it gets better after 5-6 weeks.
    Hope that helps somebody. And once again ... Happy Easter, here in 2024. Jesus saves and TIME IS RUNNING OUT! Look around you! The antichrist is on his way!

      Me, too, TCasteroil. I had to have my new '64 Super Reverb serviced back around 1965 and the dealer I bought it from, loaned me a new Bandmaster. I was playing rhythm at the time and it sounded so much more tight and solid for chords, than did my SR. I knew the closed back cab helped that; but even at 16-17 years old, I could tell there was something about the electronics that helped out that tightness. Of course, back in 1965, the average player had no clue about rectifiers and SS rectifiers.

    It's amazing to see how warped that piece of phenolic is! That was normal for vintage Fender amps until they started dipping them in wax to prevent the moisture from penetrating it causing it warp. Sometimes the warping can be so bad that it breaks the connections on some of those resistors, and that causes intermittent problems.

    New subscriber. Really enjoying the channel. Have something on the bench here regularly (usually one of mine).
    Gave the comments a quick perusal, but did not see mention of the tube chart code on the Band Master...looked like "QD" (?) which would be April 1967. No matter, just a 'technicality'. Those can be wrong, too: I have a '66 Vibrolux Reverb that has "OA" (January '65); none of the typical parts bear a number in 1965.
    Keep up the good work and I'll be tuning in. Thanks, man!

    Hi, I find your videos very good and informative. I wanted to ask you a couple of questions about my Bandmaster 1965. The plate voltage on mine seems very high. It's 484 volts on the plates. Just wondering if this is normal. Seems very high compared to yours. I replaced the output transformer and choke with a Magnetics Components from Chicago. The output transformer was way off on the readings , so I replaced it and the choke. Power transformer seems very warm to the touch running. The amp sounds ok playing it, but I'm a little concerned about the high plate voltage. Also wondering about the bias cap. I changed it as well to a 100uf @ 100v.

I have replaced the output transformer in mine with a Classic Tone 40 watt magnetic components Inc. Brand. I have read and seen on CZcams that say you should be aware that yout transformers could over heat and you would be replacing them. I believe the JJ'S are 1.3 amps and 6L6's are .9 amps. I would appreciate your advice on this. I did actually try the JJ'S for a short while and the amp sounded great, but I turned it off shortly after fearing I may b.ow something up.

    How do you bias an Ampeg SVT VR? Ampeg has a video online, but it deals with the SVT Heritage and all you have to do is use a small flathead to adjust the pots to get the two leds to light up. The VR has the two leds, but also comes with a balance pot that has to be set. What tools do I need to do this and how?

    Hey Brad. Great videos! I signed up to the channel. I've got a '67 BandMaster that is exhibiting a peculiar phenomenon which I'm having a hard time figuring out. The Phase inverter 12AT7 plate voltages are wildly off the charts. The first plate (through the 82K resistor) tries to run at almost 400V and the other plate (off the 100K resistor) drops down to under 190V. I replaced both resistors to no avail. The incoming voltage to both resistors is spot on at 430V. The voltage off the cathodes is low as well around 65V. I replaced all the coupling caps and nothing seems to do any good. What am I missing??? Thanks for the great videos!

      Just hit a note or chord and bend your neck forward a little. Lowers the string tension just enough to get a little vibrato. The neck is an oft-unused source of vibrato. You can practice by just hitting chords and shaking the neck around and see how it behaves.

    • @TheGuitologist
      @TheGuitologist  Před 5 lety

      It probably means your plate current is set lower than it should be. As you lower plate current, plate voltage will increase. Plate dissipation is really what matters. Max plate voltages on datasheets are something you'll need to worry about when you're selecting a power transformer or designing a power supply. Assuming all of that stuff is original and of the correct value, shouldn't be anything to worry about. Just set output bias for proper plate dissipation and it doesn't matter really where your plate voltage is.

  • @maxsalasr
    @maxsalasr Před 7 lety

    Sorry for the random question but, do you have any particular brand of tubes that you think sound better than others? I don't notice much of a difference honestly. Even when I upgraded from the stock tubes to supposedly high end, I still think the amp sounded pretty much the same. Preferred brand for preamp in a say ac30? Your preferred for power in say ac 30?

    • @TheGuitologist
      @TheGuitologist  Před 7 lety

      Tubes will have some variations of tone, mainly due, I think, to the capacitance between elements inside the tube and the size of the elements, etc. Sometimes tubes will be slightly microphonic, which can color the tone as well. You should listen critically to different tubes without worrying bout the brand. Sometimes the cheapest Chinese tube will sound magical in an amp, and sometimes you need a NOS RCA 7025 to sound its best. It's a subjective thing. One thing I will say about tubes from the golden era of vacuum tube technology - the 1940s-1960s - is that the tubes from this era tend to be better made with more quality control attention paid in their manufacture. This is true for tubes from both the US and Europe.

    • @wildbillhackett
      @wildbillhackett Před 7 lety +1

      I don't know how you feel about modern JJ tubes, but I think their 6L6 and 6V6 power tubes are among the best I've ever used. The only ECC83 (12AX7) of theirs I tried sounded nice but was noisy. I think the RCA 12AX7 tubes that they made for Fender (says Fender in red script) are excellent too. Those are the only modern tubes I swear by. They sound great, are inexpensive, and last a good long while.

    hi, i followed your instructions on mine, thanks a lot, its way better now.But i have lower b+ a 434v vs you 445v.My wall ac is at 122v ac.The ac before retifier diodes is at 340ac before the rectifier diodes and 434v dc after.On standby, the readings were 344 ac before and 453v after.I think the rule of 1.414 should apply ( so it shoud be 486v) so, i think i must test those diodes and maybe change them ? OR ? thank you for answering please

    I have a 1964 Super Reverb and the bright switches lack the white border around them. Everything else looks normal. It's an awesome sounding amp. Also , this was an excellent video. Thank you for sharing the knowledge.

    • @kidlargo1
      @kidlargo1 Před 5 lety

      I think he's hinting that those are allegedly in the 1st production run before they put the border on. I've seen 1 on eBay and 1 or 2 on Reverb. And while I'm here, at about 18:20 when you come back after cleaning up a bit you never refer back to what was causing that buzz/hum. Also my Vib unit makes a thumping like the sound you had but 10 times worse. It's like a frigging helicopter. Any ideas? I pulled V 4 & 5 and it stopped. I didn't have any more tubes but I do have some new ones coming. If they don't clean it up yo have any idea what else to look for? 69 Super Reverb just to be clear. Thanks.

    Your channel is super cool and interesting! As a european watcher (Austria next to bella Italia) your pronounciation of „tremolo“ makes me kind of shiver;) but its ok because you are one dedicated and helpful man!!! All the best for you and your family! THX for your work, althoug some Italianos are maybe laughing ;) Those picky fuckers!

  • @btm240
    @btm240 Před 7 lety

    do those wires (14:12) running along under the posts need to be twisted like that. the black/brown and yellow ones are twisted from the board up to wherever they go. are those wires running to the pots? maybe that is the preamp ground buss??? thank man.

    • @TheGuitologist
      @TheGuitologist  Před 7 lety +1

      Those are going to the tremolo controls, I think. Twisting probably isn't strictly necessary in that case. It might suppress some noise, but more likely it is as much for neatness.

  • @therugburnz
    @therugburnz Před 7 lety

    Back in the 80's (when you couldn't sell these for 30 bucks) I was given one of those amps. I used it for trying out different preamplifier mods. I even tried adding more power tubes (not for long) but not the OPT so I put it back original. I don't recall what happened to it after about 94. Hope somebody found it and used it.

      Wish I kept that one now. Don't know what it was about it. It just had an aura, a mojo that really just "worked". But, I'm a rambling man. Guitars come and go...but the music remains.

      I love this thing. Got it for very little. I buy and sell, and I kept selling my cabs as fast as I could get them in. This one I decided to keep for demo purposes. It's working out great so far. Now to upgrade my sound capture, and I should be in business.

    I'm really after a Early SRV Vibroverb/Superreverb Blackface tone. Vibroverbs are way too expensive. Wanted to try and get a head instead of a combo because the weight of the amps is a ton and have a 1x15 cabinet with a vintage JBL D130 1x15 speaker. Which fender head would get the closest to a Vibroverb/SuperReverb SRV "El Mocambo" tone. Yes I know his tone is in his fingers. Heard that one alot. I get that. I have a pre cbs strat and I'm looking for that amazing clean tone he had. I also love Rockabilly and Surf. I would be grateful if someone could point me in the best direction. Bandmaster ? Bassman? Showman? Twin Reverb? Silverface Deluxe Reverb head? Any of them get me close with also a great surf and rockabilly tone Effects wise with alot of twang and bite to the amp? The pandemic makes it hard to try them in person currently

    • @TheGuitologist
      @TheGuitologist  Před 7 lety

      I use all fingers except the pinky. For faster runs, I tend to use my index fingernail as a pick. Here's a video explaining a lot of my fingerpicking style: czcams.com/video/EZE0CTiuMn8/video.html

    Brad do you really advocate 70% PD? I thought vintage Fender was bias-until-there's-no-crossover distortion and that was typically 50% or so ..
    Is there any sonic benefit? I can't say its significant enough for my ears to justify cooking the power tubes 2x as fast.

    You touched on something here that has really been bugging me lately. Vibrato vs Tremelo. In my mind they can NOT be the same thing. How can they? Isnt one a variance of note pitch and the other a variance of note volume? I would really like to undertand what the deal is.

  • @markharper8913

    last year i sold a 64 black face Bandmaster. this amp looks like a silver face era not a black face. I still have a silver face that I bought back in the 70's. Still has that clean sound and is flawless. It's trem alo with the emphasis on the trem. Not the olo. lol
