[Amps] Screen voltage regulation

[Thomas Hoeppe]

Hello guys,

I am new on this reflector, so may be I am asking a question whitch has been discussed before.
I am looking for a simple design for the regulation of a screen supply. I need 800V and about 50 mA. I will have to take care of some negative current, so the supply has to be able to do that or I will use a 100mA supply and allow 50 mA of current through a resistor to ground. My anode voltage is 5 KV, so I don't want to get the G2 voltage from the anode voltage. 

I am looking for easy and rugged solutions. (KISS.......keep it simple and stupid!) 

Any ideas?

Thanks in advance.......
