Oh so close, but now what (new problem)

All you will see at the collector terminal with the HOT removed will be a DC voltage, around 150V or so.

You should see a horizontal drive waveform at the base terminal, but without the B-E junction drawing current, the waveform probably won't look right.

Okay. Just trying to figure out what kind of testing I can do while waiting for the new HOTs to arrive. I'm pretty sure I blew it up when I shorted the wave shaper transistor. I'd like to test the wave forms of that module to make sure it's working properly before I put the HOT in. Hopefully the waveforms of that module will be unaffected by the removal of the HOT.
