The power supply is used to power my SGC 500 solid state amp . The earlier power supplies would cause noise and hash on the hf bands . The newer power supplies do not cause any noise or hash on the hf bands at all . From 160M-10M all is quiet . I gave it 4 stars because of the power switch is located on the back and not on the front .
