Jay,
Where am I testing for the 150V on the OA2's? From a pin to ground or across two pins?

Across the 0A2 pins anode and cathode.

Between chassis ground and pins 7, 2, or 4 (internally tied together) you should see -150VDC on one OA2, and -300VDC on the other OA2. Higher voltages (+10% or more) mean that tube is not working.
