I have had that happen on radios that had been overheated and needed the lead tabs resoldered on the output transistors to get the power back up. maybe not your case though. Usually most radios will make more than their rated power especially at higher input voltages. Sometimes not for long

Tom, It appears that the final transistor Q2740 is dead, and the driver transistor Q2730 is running wide open. The driver normally provides about 13 watts to the final. Check all solder joints and verify the correct DC voltages are present during transmit. An RF millivoltmeter can be a great
