  • The RCA A78 is an AC operated combination automatic phonograph and BC/FM band receiver.  Has both a 45 RPM turntable and a 33 1/3, 78 RPM turntable.  The 45 RPM turntable used is model RP-168, which holds up to ten 7 inch fine groove records.  The 33 1/3, 78 RPM turntable used in this model is 960282-1 , which holds up to ten 12 inch or twelve 10 inch records. The 45 RPM turntable is in the upper compartment and the 78 RPM turntable is in the lower compartment.

    The BC band frequency range is 540 to 1600kHz.  The FM band frequency range is 88 to 108MHz.  Uses Qty(3) #51 lamps, two for the dial and one for the jewel.

    Has built-in AM and FM antenna's, with provisions to connect an external FM antenna.

    The chassis RC-1084A is shown in a schematic (from Riders) for the models A78 and 9W78. On the same document one can see a cabinet which there is called PH 471. For neither name a Rider's, Photofact or Beitman could be found. The 1950 RCA Victor Service Notes manual make no metion of a model 9W78.  The four knobs are Power/Volume, Tone (treble, normal, bass), tuning and selector (FM, AM, PH, XPH). By the way: It was in the early 1960s when RCA Victor called a budget label of records "Victrola" like its first console phonographs.
