Newb quesion on elevated heater supplies:
How do you do it? I got an SRPP here waiting to be tested, but the cathodes are a good 200V apart and I don't know what the best way to float my regulated DC heater supply is...
There's some transistor-based DC reference circuit in the Morgan Jones book, but I'm not sure I understand how you actually use it (plus it seems too complicated).
Is there an easy way to raise heater supplies? Using a zener somewhere, maybe?
:?
Peace,
Al.
