I've got a Yamaha B-2 100wpc power amplifier that came in a few weeks ago. I finally got around to it this weekend to see what the issue with it was. It appears that someone damaged the speaker selector board in the amp, as the circuit board is completely cracked in half, and then poorly glued back together and wires jumping the broken foils.
The 4 mechanical buttons on the board are also shot, loose and sloppy, and bent. So, the amp doesn't really work as a result...
I am wondering if anyone knows where I could get new, better quality buttons, as well as possibly getting a new PCB made up to replace the cracked one. It's a small board and rather simple so it wouldn't be hard to make a new one for those who have the ability.
Any suggestions & help would be appreciated, the amp is in minty condition and weighs 60+ pounds (which I find a bit crazy for 100 watts per channel in a 2 channel amp, but hey whatever, lol) I would love to get it repaired, I have the matching C-2 preamp for it as well so getting the amp going would make this a nice little setup!
