Jim, et. al.
A Heathkit amplifier Power Supply is a voltage doubler. The winding is
rated for 1170 VAC at 1 amp CCS with 234 VAC on the primary windings. Using
a voltage doubler, it gives about 3250 VDC with no load, dropping to about
2800 VDC at a peak of about 700 ma full load. I would look further for
something to power a 4-1000A.
