The 30k Ohm load pulled this down a lot.  The 30 us pulse peaked at -350V (from 7.5VDC input level).

This might yield 1200V at 28 VDC input level.  So the transformer will have to be bigger
wire probably to let that much power through.  A quick back and forth with Ningbo Eilux Electric Appliance Co., Ltd.
while I had some insomnia confirmed my measurement meant the small transformer was hitting
the saturation limit if dialing up the input volts stopped giving more output volts.

A push pull arrangement helps this situation.   I'm making a circuit to test that, and maybe testing a
bigger similar laser printer transformer today.
