I got to the root of what I thought might be an assembly problem with
the push drive chain of transistors and it was that Pa1 from the MCU
was on at the start and PA2, PA0 were not.  It can be tricky not to be fooled
by some things when working on a circuit with mods from the schematic
and done with wires.

Making a little code change and testing again soon -- very close to having good
equal strength pulses to get HV with.
