Just bought a Harmony H305 for a hundred bucks. Orginal Jensen 12 speaker, 2 12AX7's 2 6v6's. Within the last couple of years it has been recapped and retubed and also had a 3 prong cord installed.
It was not working when I bought it and I found one of the spades in one of the phase inverter socket was broken. I did not have any luck soldering it back together but tested the amp with a jumper wire from that pin on the tube back to it's intended circuit. Can the little metal connectors be bought or will I have to replace the whole tube socket which I would rather not do?
I am getting near instant distortion when I dial up the treble knob from zero too.
Still looking for a schematic, the one on the baffle is about 30 Percent gone. May have to reverse engineer, but at least it is a simple amp with no reverb or tremelo. It has great tone when clean and when the tubes are overdriven. Perhaps only loud enough for a coffee shop without being miked.
Thanks
