Can you please clarify this for me. What do you mean by across the
signal? Do you mean tie the collector to the signal and emitter to GND,
and pump the base to shunt the output to GND to mute the output stage?
or do you mean in series with the output and the load? That case it would
be output connected to the base and emitter to load?
still fuzzing around.....
