Thank you to everyone for the help! Got it up and running this weekend after a full re-cap and replacing the out of spec resistors. I'm super excited to set up the three Bandmasters and give them all a go!
I understand why people say this, I do. But for me, I never buy something like this without the intention of tinkering with it. I leave it up to you guys to preserve history. I’m going to be dragging this thing on the road, so it’s going to get abused anyway.
Nothing supremely invasive or irreversible. Tremolo cut push-pull, three prong cable, recap, and moving the tremolo to both channels. Nothing that can’t be undone.
So, would you have a suggestion as to why I’m getting 179 volts between a single side of the heater and ground? Just so I know which repair (new ground connections, new electrolytic caps, new anode lode resistors) actually fixed it.

I recently purchased three 60's Bandmasters from a local vintage guitar shop. Two AB763, one AA763. I've been in the process of doing some of @robrob 's wonderful mods to each of them along with a Quad Reverb I bought. All are done except one.
I've opened up the last Bandmaster (the AA763) and...
Hello lads. Got a question for everyone out there. I have a pair of Ibanez TS-10 pedals on my workbench. One, simple enough, had a loose joint on the power supply plug. The other, has a sticky footswitch. Not the actual internal switch, but the plastic latch that triggers the internal switch...
Hello!
Thanks to this wonderful forum, over the last two years, I've been able to enter the amp building community. I've finished about eight builds now, and, with each one, I've gotten better and better. The other day I picked up a Super Twin/Studio Bass chassis for next to nothing. No...
Exactly. I'm not going in on a bass worth anything. When I first started refinishing things, I didn't start with my SG, I started on a cheap import. Same thing here.
I just like to get multiple opinions before I undertake an endeavor. I've considered using the rasp and file method or just going the extremely slow but arguably more precise route of simply sanding. I just want to know what everyone else has done.
Hope this is the right place to post this. Our bassist has a set neck Thunderbird clone that has a crazy fat neck on it. The closest I've ever seen to being literally half a baseball bat. How would one go about shaving it down? I consider myself fairly competent in these areas, but I tend not to...
I've got a fifty watt 1977 JMP that I plan to use with this, and the L-Pad is 100 watts.
And do you have any suggestions on how to redraw the diagram to put the speaker out disconnect switch in a safer place in the circuit?
I'm attempting to put together an attenuator which can double as a load box and with line out. I've got this schematic I put together that I was hoping you could look over and see if I'm missing anything or doing something wrong. I'd like not to blow up any of my amps in testing lol.
The...
Starting a few years ago, adds for some interesting guitars started coming up in my facebook feed. All of them were in interesting colors, supposedly setup in the US, and priced dirt cheap. Like most of you, I wrote them off without wasting too much time. As the old saying goes, you get what you...
Popped in the new Copper Cap, and it fired right up no problems. I had it biased a little too cold for my tastes initially, but after warming it up a few volts, it sounds exactly how I hoped it would. A couple of friends are already wanting them. Thanks for the help gents, I appreciate it.
I haven't as of yet, I'm not super familiar with their forum as opposed to you guys, as I have had a lot of good luck here. Lemme find a schematic link.
