Hi all - I have a dead 800RB on my bench with a bad transformer. This is an older unit with the horizontal power switch. I have been in contact with Gallien Krueger tech support and was told that they do not stock the transformer - that they do not have a part number and do not know of a suitable substitute for it. I was a little surprised but OK, this is an older unit - but not THAT old there wouldn't be people still using these amps or that repairs didn't need to be done. So I'm reaching out - can anyone advise me on a transformer replacement for this amp? I can't even find specs on what the output voltages are supposed to be (zero, right now, because it's dead), but I believe one of the outputs is supposed to be 85 volts before it hits (one of) the rectifier(s) - but I couldn't even tell you which rectifier that voltage is supposed to go to even if I had it. Anyone? Dead RB800 lying around with a good transformer? Luck with a replacement tranny?
