Default Solid state amp on +/-150V ?


I'm looking for a schematics for solid state amplifier that has about +/-140V - +/-160V and uses IRF's on output stage.

I was considering moding the old Crescendo amp, but I really don't want to experiment(too much).

So, if anyone has any schematics at all for such high voltages, please post it here.

Default a couple thoughts:

you can go to and look under electrostatic amplifiers. The Art of Electronics also has a regulated high voltage supply -- if you change the reference input to a pre-input you can use it to drive capacitative loads. The Art of Electronics article has some now-discontinued Motorola devices, but I am sure you can find suitable replacements from IRF.
