Yes, I only like to fix a problem once. Varo used to make some nice
3 KV PIV rectifiers that looked like the larger microwave oven diodes.
They were great for upgrading old broadcast and high power commercial
two wy radio systems. Using four of them and moving the meters allowed
me to reduce two full six foot racks into a single four foot outdoor
rack. It was bolted to the base of the tower and was still in use when
the owner died, years later. I did all the HV wiring with 25 KV second
anode wire.



Jeez, how big were the seleniums? The biggest ones I've seen were only a
couple inches square.


I've seen high current ones that were almost six inches on a side.
