OK kids -
Here's the update:
1. I'd accidentally wired a couple of things wrong, causing the strangled sound and "runaway" gain on the cut control. This has been fixed, I think - Channel 2 now sounds pretty good. This fix also eliminated the tone position 3 problem for whatever reason.
2. I STILL get signal from Channel 2, with the MV engaged and gain control above 5 or so. Approximately as loud as conversation. From what I understand, the C-30 should be totally attenuated when turned all the way down.
3. I thought I had wired the jewel light backwards. Swapped the heater wires - still no dice. What's the best method for measuring heater voltages??
4. Voltages from V1 to follow.
5. This is a LOUD amp.
I can post photos of Channel 1 if you guys really want, but it's the GF's camera and she's kinda protective.
