Building QRP Labs 50W Amplifier

Описание: This short video describes the building and operation of QRP Labs 50W amplifier for the QCX line of qrp transceivers. The amplifier requires 20V to deliver the full 50W. I built my amplifier for the 40m band and with a 13.8V PSU, it delivered over 30W. I substituted the supplied IRF510 final transistors with two similar IRF510s
