I got me one of these at an antique store for roughly $30, and decided I would convert this into a guitar amp for funs. I switched out one of the speaker outputs with a 1/4 jack, and I hear crackling and such when I turn the knobs, but I am getting no sound from the input jacks. All the tubes seem to be working, I switched out the 6AQ5s since two were shorted and I also switched out the 5Y3 and 12AX7. My question is mainly about the 5879: do I need to keep this in the circuit to work? I read somewhere that it was not needed, but I am unsure. I looked at the schematic and it seems to be bypassed? Any help is appreciated.
