Serviced with new filter caps and ready to be used as a little guitar amp. Tubes are all original to the unit and date 1952, 6SJ7, 5Y3 and a 6V6, like the old champ amps. One input and a tone control, this amp has alot of nice distortion and gain and resonable volume. The circuit is original, but the phono input has been disconected. 3 prong power cord installed.
