AMPVHF - New 500+ watt vhf amplifier solid state This amplifier is new I’ve never used it,not even once other then Ka9tsd made this for me and is set on 220v at the moment. I don’t have a 220v Set up in my shack and not going to put one in either since we are planning to move This summer. Amps good from 143-148 MHz All mode am,fm,usb,lsb and is automatic When keyed it needs no switches just goes. Runs two mrf300 ldmos transistors at 50 volts. Power supply is over kill and is an awesome amp. At the moment the plugs set for 220 but will run on 120v just change the plug only. Has auto rx/tx switching with over drive protection to 1000watts. Amp Also has low pass filtering. 5 watts in 500watts out,amp will do 600 watts if you run the voltage up But I figured I’d cruise it at 500 at 50volts.Super nice amp $1300 shipped or Best offer... Getting into other electronic things at the moment.
