Why would you want a PIN diode? That relay doesn't handle RF, its to KEY
the PA control circuit. You could replace it with a transistor, either
bipolar or FET providing the PA keying circuit was at a compatible
voltage (including polarity) and current. The relay has some versatility
that way being polarity insensitive and at least one amp, the Collins
30L-1 has a negative keying voltage with significant current. Negative
like -120 volts DC.

I thought this had probably been covered already but I cannot find
anything about it in the archives or by Googling. Has anyone replaced
the amplifier relay in the Corsair II with a PIN diode? I read the
different ways to silence the relay but nothing about replacing it with
something else.
Thanks,
