I am trying to troubleshoot a Tugicom 25 watt FM broadcast transmitter. It's output has dropped to 1 watt. I replaced the
power transistor on the PA but it didn't make any difference. The voltage supply to the PA is what it is supposed to be ( 26 volts).
The PA is fed by a 1 watt driver. I am not sure what to measure/ do next and have not been able to find any other resources to
help me out. Attached is the schematic for the PA, I don't have a schematic for the driver board. The transistor on the PA is an MRF314, the two transistors on the driver board are 2N4427 and KSP10 . Any help would be appreciated.
