[TenTec] Corsair II Amplifier Relay

[Dr. Gerald N. Johnson]

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.
