High voltage power supply 2.6KV

Designed for an He3 Neutron counter.

The transformer is ripped from an Electronic Fly swatter.
The UF4007 diode is the fast equivalent of an 1N4007.

For the 200M feedback resistor you should use one which is designed for high voltage. If you can't find one, it's possible to connect 10 resistors of 20M in series.

To avoid electrocution the opamp is added to create
an monitor output.
