[Milsurplus] SS Power Supply for WS 58.. more

[J. Forster]

I should add a couple of things:

The CT of both transformer primaries goes to the +9 V battery connection, and
both primaries are connected in parallel, through the MOSFETS to Gnd.

The secondaries (normally the 120 VAC inputs) each go to a 4 diode, FW bridge
and filter cap, so the inverter makes 2 separate 90 VDC supplies. These are
connected in series to make a single 0-90-180 supply.

The Cockroft-Walton for the -ve bias uses the voltage on the transformer
primaries.

The transformers are run BELOW their rated flux densities (9 V  100 Hz square
wave rather than 12 V 60 Hz sine) [9/12 x 120 = 90]

AND--  before anyone asks  --  This design will NOT work to replace a WS 19
vibrator. That issue is a whole lot more complicated.
