Tubes and power supply

[Sasha Sekulich]

Howdy!

I'm primarily a guitar player and like the sound of the tubes
(especially hit with a large hammer, but that's not important right
now). I have about 15 schematics for various tube pre-amps, which are
farily similar in design, but greatly vary in the plate voltage area.

So I thought - I'll make a single pre-amp and a power supply which could
vary the voltage from, say, 150V to 600V. But, all the IC's I know of
are for voltages of up to 30V, and there are few transistors that can
endure such a high voltage. And I'm not into regulating it directly with
a pot. And I'm not that good with electronics (not to fool with 600V
anyway).

Does anyone have an idea how to make the above-mentioned power supply or
could someone design it for me (I'd be eternally grateful - ok, most of
my time using it, actually)?

TIA, Sasa
