Hey Dave I had this exact thing happen on the 6300, and what it was was that I had T'd off the logic on the PTT lead from TX1 to another T/R relay for a receiving antenna.
I solved the Amp issue by removing the 2nd device, replacing the 6300 with a Flex 6600 and then using the TX2 ptt line on the 6600 for the receiving antenna TR relay (ok, I got carried away). Short story was that the keying line was not going fully to 0v. Might you have done something similar?
