[Amps] premade HV rectifier board

[donroden at hiwaay.net]

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.
( looks like a large ear of corn )

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.
