My 65 lb.1/2 stack of Fender tone! I have other amps but this is my #1. I bought it from a guy who painted bikes for a very famous motorcycle club. The tubes would light up but no sound. I bought it for $25.00 anyways. Fuse assembly was the issue. Typical usual maintenance over the years: new tubes, some filter caps, and bias. I DID NOT change it to Blackface specs. I play Punk, Rock, Blues, and Country with either a '93 Jeff Beck Stratocaster or a '95 Gibson Les Paul Standard. I easily played 250-300 gigs with it. I ride the volume between 5-6.
