Grumble Grumble Grumble ... Gripe Gripe Gripe.
I would have updated the high voltage power supply to a simple
transistor regulator. I have about 128 AC around here and that
can really give  over voltage on 115 V transformers.
PS. Where do you find a 300 V transformer ... I may build one
some day.  Also any options for a ALARM feature? Say a analog
bird chipring sound?

I keep drooling over SWTPC products... I wish that made it big
