FOR SALE: McMurdo SIlver 905-A "SPARX" signal tracer from
1947. Includes probe. Fair to good condition. It's all there. Case handle is torn up.
I found an article available on this unusual goodie, with schematic if anyone is interested.
It's basically a small 3-tube audio amplifier with built-in speaker and 120V AC supply.
Not bad for $12.00 plus shipping.
