Usually at FET would solve it, with a series resistor to adjust the sidetone level, and possibly a capacitor if it is a dc level from ground. It is many switch type FETs, those I know and have in my store are 2N7006, VN2408, VN2410, VN2222

Yaesu would probably have used a bipolar device, with questionable effect, particularly in such old transceivers as my FT-902

Does anyone know how to lower the volume of the cw side-tone on a IC706Mk2G
?

If I turn down the volume control I need to turn it back up again to hear
the incoming signal each over. This gets tedious and wakes the neighbours
when I start sending without reducing audio gain .Also may bring MI5 round
at 2.00 am with current security jitters.
