Hey everyone, I could use some help trouble shooting my speedball build. I've had the Crack built for almost a year. Love it. Works great.
I've completed the first part and the tests aren't correct.

Terminal     Voltage (DC)
OA                71.2V
IA                  185V
B-A/B            0V
IB                   185V
OB                  0V

Any ideas?

All 4 LEDs are working on circuit board, however, only 1 of the 2 are working for the  12au7 tube.
