  • Notes
  • The Radio Craftsmen model C550A is an AC operated audio amplifier for mono input (Mono Tube Amplifier). For optimum operation, the output tubes KT66 should be a matched pair.

    Model 500 is the first model of this line which includes 500, 500A, C550 and C550A. Other names like C500, RC500, C500A, RC500A or RC550A are wrong - but we have to list since so many persons look up under these wrong names. SAMS Photofact is distinguishing between model 500 and model 500A - but Radio Craftsmen made on both a number plate with only "500" as model name. Distinctive is the parts line-up on the plate. Therefore have a closed look to our SAMS reference picture when deciding which model it is.
    The C550 and C550A are the final versions of this family.
