I was afraid of that.  It looks like the mfr. wanted people to get their
replacement parts from them instead of ordering the same generic diodes they
did.  Oh, well...

At KWXY, our rectifier stacks started out at 15 kV PIV, but they have been
overbuilt to use twice as many diodes for a PIV of 30 kV.  These are not
studded, but are T6A10 rectifiers.  You didn't mention if the stud is the
cathode or the anode.  Also, what is the overall voltage and current each
stack has to handle?  Divide the overall votage by the number of diodes and
then multiply that by whatever fudge factor you desire to come up with a
voltage rating for each diode.  I believe the 1N3766 would do the job, it's
1000 PIV and 35 A, but they are fairly expensive.  If a 600-V rating is
sufficient, the 1N1206A might do.  Both are cathode-to-stud.
