>At 3350 Vdc B+ under load (only a 50v drop) at 1.2A I max out my 2000 watt
Dang! talk about good Ereg!!!!!!!!!!! The best I have ever seen is 175 volts
no-to-full load using a Dahl plate xmfr and a resonant dc filter choke with
32uF of oil filled cap. Well done old friend.
Its a Daiwa, and I've never checked the accuracy. This works out to
