 +Or, simply lift one end of Q10's base resistor and never worry about shorting a current source to ground.

 +Easier yet. Cram a piece of cardboard between the relay'​s contacts. It works and is easily reversable.

 +Improvising on the mod on tentecwiki I pulled up one end of the 22k resistor in the base circuit of Q10 on the control board and was rewarded with silent QSK.  I've never used a linear amp, so I don't need that relay clacking at the end of each character. ​ I've ordered an auto antenna tuner for the Corsair. ​ Once that arrives, I can really get busy!

 +Good Idea Jim,\\
 +When I had my Corsair II I also used a AL-80 Linear for SSB only so I needed the relay but didn't like hearing it when barefoot. Here's what I did. I use an Astron PS so never used the power on switch on the CII. I disconnected the wires to the power switch and connected to the end of the resistor so when I needed the linear I simply pulled the power switch to on which turned on the relay and the switch was still labeled correctly. Need more power pull the power switch!
