Gonna start getting down to fixing '63 bandmaster

Re: Gonna start getting down to fixing '63 bandmaster

Many years ago I was looking at getting a vintage Fender amp for various stupid reasons and a number of the guys here pointed out some good things (including TGWIF) but the key bit of advice came from Golden.

This may be completely out of line, but when you're dealing with something rare and potentially valuable- I believe, at this time, it would be a bad idea for you to get a vintage amplifier if you don't know thing one about it.

I know a repair dude who had a customer bring in a rare, valuable and highly coveted amp. The customer had a good idea of what that amp was when he bought it. He read about a mod on the intarweb. Dude installed the mod and completely totalled the amp. There was nothing my repair friend dude could do- there were no parts for the amp available anymore, the entire thing was toasted. So now the customer dude sits at home with his completely blown up formerly cool, formerly valuable and now increasingly rare non-working amp that will never work again that's worth next to nothing.

I'm not saying that you'd do something like that, just that if you don't know what it is, you probably won't appreciate it for what it is.

Wow. On second thought, I realized you thought there were clipping diodes in a vintage Fender. You may need to do some reading first, dude.

I found tons of information on the hoffman website and started reading and found an updated schematic and parts list for their boards that they used to make. Are those good to follow? I think this site has all the answers I need. I believe this wont be as daunting as I thought it would be, it's just a few burnt resistors/bias cap and trim pot/filter caps, I'm not going to rebuild the whole amp, I'm just going to very carefully touch up these issues step by step starting with checking heater wire>filter and bias section

I went over heater wire dress, as well as making sure it goes from pin 2 to pin 2 on the power tubes, 7 to pin 7. It turns out that whoever worked on this amp before I bought it soldered 2 to 7, 2 to 7 and the heater wires are not directly above the sockets as they should be. I'm going to go ahead and fix those lines right now.

I'm looking at this JJ filter cap can, 4 caps in one. Would this be dumb to use?
