But a 3-6 db pad on the input side of the amps tr relay would help a lot. So the pad is not in the RX path. Dunno if the SGC SS amp has overload c; /archives//html/Amps/2016-02/msg00006.html (11,631 bytes)

Fortunately, the SG-500 does provide drive attenuation when necessary, so ALC isn't actually required. I was just wondering if anyone knew of a circuit tha; /archives//html/Amps/2016-02/msg00010.html (10,180 bytes)
