Barry, N3LLL also makes a replacement regulator board, plug-in.
See attached.

I'm considering building Dr. Jerry's design for the solid-state regulator as
outlined here:
https://www.navy-radio.com/manuals/hsn/hsn-issue%2052.pdf
Rather than having to connect the output to the 180V test jack, I'd prefer
to make it completely plug-in compatible with the tubes. This means the
output will go though the 47-ohm cathode resistors which provide a small
voltage drop. Would it be possible to simply add a regular diode(s) in
series with the 180V zener diode (D1 and D2 for the initial schematic or
just D4 for the alternate schematic) to increase the output voltage by a
diode drop or two to do that?
Thanks,
Barry - N4BUQ
