I've made my own solid-state plug-in replacement rectifiers for a
variety of tube types. I look up the tube specs and select solid-state
diodes that stack up appropriately for current and forward and reverse
voltages. I usually end up using either 1N4007s or 1N5408s. From
on-lline sources
Steve,
What kind of resistor do you use in this type of rectifier build to
simulate the voltage drop?

I prefer cylindrical wirewound power resistors for this job (they seem
to be able to take more surge current than the sandy rectangular ones
in case of a fault downstream).

You can expect somewhat higher voltage from the new stack than the
original tube rectifier - if that is a problem for the rig, then add a
series power resistor to simulate the internal voltage drop of the
earlier tube. So far I've only needed to do that once when the new
higher B+ exceeded

Thats not a Continental Electronics product. CCA was a company that went
defunct about 15 years ago.
There are some AM1000D's converted to AM, request on the AM forum.

CCA was sort of a bastard-son of RCA after they went out of the
broadcast equipment biz. Some parts were the same, many not.
