After Much Work

The Traynor has come a long ways. The amp tech completed a bunch of mods, and it sounds fantastic. Nice cleans and much crunch when cranked. He changed a several caps, bypassed the reverb circuit (I have some questions here), added a toggle switch to bypass the tremolo circuit, and added a feedback loop. The feedback control is nice. When dialed up the tone is much fatter. I dismantled the head cabinet, re-glued all the joints, replaced the tolex, replaced the grill cloth, and sprayed in inside of the cabinet flat black. It's much prettier, but the rubber/chrome bumpers on each side look awful. The new speaker cab is done and I replaced the JBL D-120 with a JBL E-120. When cranked the Traynor would likely vaporize the D-120. It a fantastic setup that seems to be able to do it all. Even fits nicely in my office.

I have a couple of question if anyone cares to spend the time to look at the schematic. There is a significant tone and volume difference between the two inputs. Since it's a single channel amp I thought they would be the same. Also, even though the reverb circuit is isolated there is a constant echo. When I disconnect the reverb tank the echo is gone, tone is pure, volume goes up, and there is a hum. Should I somehow ground the two RCA plugs from the amp that go into the reverb tank to eliminate the hum?
