I'm setting up a Mastr II VHF station for a 2 meter repeater and when I got to the power amp to check everything I can only get about 86 watts out of the 110watt PA. I noticed that the power supply starts to fold over at about 20 watts out and when I get to 80 watts the supply is only at around 8 to 9 volts. This Mastr II station has the PLL exciter but they gave me a 4 transistor power amp the original amp was missing. This is the newer type station with the IDA controller. I looked up the model number of the supply and it's a PL19D430272G1 Rev 4 which shows to be the right power supply for the station. I don't have my spectrum analyzer at the moment so I can't tell if the power amp is spurring although station metering shows below rated current on transmit. Any clues?
