Hey Now !!  Im not really up on amps but would like to know if anyone knows about these old amps. I just got a Schafer chorus 303 guitar amp for 40 bucks .. It is large and heavy on wheels has 2 early Cerwin Vega 12" speakers. I can find no info on this company anywhere. Looks to be by the speakers late 70s or early 80s. Has a real sweet sound and is a power house .. Any info would be appreciated !! Thanks all !!
