Palomar FET 250 High Drive Linear Amplifier, DNJ Radio
High drive amp that will work with a 10m export mobile radio, class AB bias design, and you got it at the right price. Just don't over-drive the amp's input with too much power output from your 10m export radio - and it should run fairly clean output. Drive it until you see about 200 watts PEP on SSB. That should be an efficient power level for the two ERF-7530 MOSFET devices. Same goes for the output for AM use. However with FM - adjust the radio output until no more than 40 watts output from the amp . . .
