? Thanks - I hadn't thought about a fault in the bias pot.
? I think the recommended bias adjustment is for a 250 mA increase in draw. After replacing the IRFZ24s I always reset the bias pot to minimum, set mode USB, mic 1, drive 1 and adjust bias pot for about a 250 mA increase; as specified on sbitx.net.
? The adjustment is very sensitive and suffers from the same heat creep that makes power calibration difficult.
