I decided to redo my old 1.25kV PMT Bias Power Supply. In particular I wanted the supply to run without a central power supply and added a small transformer and linear regulator so I can run it off mains. I also replaced the TNC connector with two safety 4mm banana connectors. The voltage divider for the multimeter is now on the HV board itself, rather than floating in the air.
Otherwise I reused most of the old components, the old PCB and also the front panel.
Please ignore the test leads on the transformer, I only have those there for testing.
