Can someone point me at a supply for the attached hybrid amplifier? Any kits out there that would work well for this design?
High voltage bipolar power supply kits aren't common but Tubecad does offer one that would take care of the +/- 100 volt supply needed for this circuit.

And this one would probably work for the +/- 28 volt supply.
