  • Remarques
  • The Radio Craftsmen model C550 (RC550) is an AC operated audio amplifier for mono input (Mono Tube Amplifier). For optimum operation, the output tubes KT66 should be a matched pair. The sound of C550 is believed to have a better bocy but not as transparent sweet and natural than C500 and C500A bcause C550 is operated in Ultra-linear instead of triode operation, the output also increase to 30 watts instead of 15 watts. The Amplifier uses a B+ delayed turn-on via a slow warm-up. It requieres 60 seconds to preserve the cathodes on the KT66s. Design Bob Grodinski.

    The Radio Craftsmen model 500A (number plate only 500 !) is an AC operated audio amplifier for custom installations with one (mono) input (470 k). For optimum operation, the output tubes KT66 should be a matched pair. The line transformer has 3 positions for line voltage.

    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 pictures when deciding which model it is.
