I am rebuilding a Hammarlund HX-50 transmitter and need to replace some
diodes. CER73C & CER70A are the part numbers on the schematic. I can
probably pick parts that would work, but I would like to know if these
numbers are industry standard numbers and if data sheets exist.

I know they are industry standard numbers, and I have drawers
full of them in the cellar someplace. If you do a Google search
you can probably find the original specs.

NTE crosses the CER73 to a 1000 volt 1-amp diode,
and the CER70 to a 600 volt 1 amp diode. (NTE 125 and
NTE 116 respectively.) If it were my TX, I'd go with 1N4007
diodes, or even something with a bit more current rating.

If you want originals, I could dig in my parts bins, but that
might take a while
