Micro Bassman Build

Well, for sure V2A is dead ... so that explains the loss of signal. I wonder if that tube was already bad from the start as the amp never had a lot of volume, like even for a tiny basement amp. I'm waiting on two replacement 12AX7 to try one in V1 also.
Voltages looked mostly spot-on, I'll see again with the new tube.
Only thing, heaters are at 12.6V instead of 6.3, not sure what's going on there.
