I have several of what I call "the last diode stack you will ever need".
Twenty-one of the following diodes in series arranged in a circular
pattern around an insulated core and mounted on individual double
heatsinks.

21 x 1.2kv = 25,000 piv rating at 40 AMPS PEAK / 25 AMPS AVERAGE.
Unsolder one connection, feed the transformer leads to the center of
each pair of 10 diodes and you have a full wave bridge each leg 6,000
piv @ 25 AMPS
Or 12,000 piv per leg Doubler or Full Wave Center Tap.
I may have five left.

Quoting K1SG@aol.com:
FAR Circuits makes a variety of power supply PC boards; you can select the
board you need and populate it to meet your requirements. I designed a
rectifier board using 6A10s for a 6 KV supply that FAR sells for pretty
reasonable money. Just be careful; as noted before on this
reflector, there are
at least 2 diodes using the 6A10 designation. One is only good for 100V, the
other is a real 1 KV, 6 A diode.

Does anyone know a place to buy premade HV rectifier board etc for HF
