[Boatanchors] [HallicraftersRadios] Hickok 600A

[Walt Cates]

Yes, The web is full of solid-state workarounds for the 83 rectifiers. I have done it, it works. My raw B+ and bias voltages are dead on. I have the operations/calibration manual. That was not my question. The secondary AC voltages are reasonable, reflecting today's higher line voltages. I am just curious about internal voltage readings with different switch settings. I can calculate these things, but in my lazy old age I was hoping some one had done that work for me.

A majority of acceptance is not proof of correctness.

FWIW, the 83 is a full wave mercury vapor rectifier. They have a
typical voltage drop of 15V regardless of current. Filament is 5V @
3Amps. Since silicon rectifiers are cheap one can simply series several
to obtain the right voltage drop.
There are probably data sheets on the web, I looked in a very old
RCA handbook to find it.

I have the manual with the schematic. But, there are no voltage notes or
