Progress rpt:
1. Received, installed & checked out new (proper) contactor. Same
day received, happened to look in another junk-drawer & found 2
contactors I could have used all along. Hellooo... Murph'!
2. Checked out rate-oscillator; 1 transistor backward, 1 resistor
too small. Now OK.
3. Checked out +12 & +5 arriving at main assembly from controller assy; OK.
5. Taking a breather before tackling the worst of it: getting all
the IGBT drive-hardware & burst-width ckt to actually work. After
that, if&when, hit it with the HV--but gradually thanks to the big Variac.
