Went through the shelf of Iron and parts:
1.5A/54.5-0-54.5 volt power TX. Full bridge, CT grounded
2x 15 Hy/75 mA Hammond chokes( mmmmmmhhhh, matched pair! )
coffee tin of 120 uF photo flash caps
50k, Audio taper Noble pot
Sleeve of DN2540N5 Mosfet's
6 uF/220VAC Vit-Q AC caps for output coupling.

The PS will yeild about +/- 40V. I think I'll try a 10 mA idle current for less than 1/2 Watt dissipation per top MOSFET and run w/o heatsinks.

I have everything but the plate to mount to. Looks like a nice simple job at this time now. I can't wait to get it underway so I can put it In-System and see how it compares to the All-Valve version.

See anything I missed? Diodes? Anybody have some nice diodes? 200 PIV/2A Schottkey?

mmmhhhhh, no heaters!
regards,
Douglas
