I always add a muting circuit to old receivers. Rectify a bit of filament voltage and run it to a relay that does the same thing as the transmit receive switch, or removes B+ to some stage.
If you worry about resale value, you can just tack wires onto things and re use some terminals on the back of the radio for the muting wires.
