Would that mean that I could use a transformerless voltage multiplier as 
supply for your circuits? (A high frequency square fed into a poweramp and 
then into a diode/cap cascade)
Would you recommend that or a switcher? 

How much current does your VCA draw at 50-100V?

I thought pentodes need a high voltage on the screen grid?
