    The OT secondary should not matter if it is only two wires and negative feedback loop not in the circuit. I always use black for ground and the green for signal.

    What OT are you using?

    Sure does.

    If this were my amp I would go through and do all the wire adjusting/shortening you wanted to do first, then continue on with troubleshooting. That way you'll be checking each wire and component as you guy and you may fix it during that process.

    If you want to get it running, I'd highly recommend now is the time for signal tracing.

    What did you change?

    It now sounds like there may be multiple issues going on.

    In the previous picture, are you making sure to plug into the left most jack?

    Everything is good except for a slight hum. Found the source of it.....naturally on the bottom side of the turret board
    Will fix later

    Paul it sounds like you have a cold solder joint somewhere. It makes contact and you are good, heats up and then moves a bit and no contact. Check continuity and reflow the joints, I actually have a magnifying glass that I look at the joints with. It helps to see if the edges really grabbed to the component or if they are riding on the top.

    After a fresh start this morning I realized that after shortening and rerouting some leads and cleaning up some joints, I had connected v2 leads from pins 7&8 backwards. Sound is good now. Still have a hum that increases and decreases with volume control.
