G7DES mic pre-amp
Anyone who knows or knew Geoff, G7DES?
The image shows a little pre-amp that's come my way - I don't know how or why or when. It has input for mic, a PTT input, space for a LED and for no known reason one of its 2 transistors is unsoldered and the other has never been fitted. Is this a known design? Anyone else use one? - or need one? Graham
