  • Anotaciones

  • RCA models 6-BY-4A and 6-BY-4B are combination portable superheterodyne reciever and 45rpm record player. -A and -B models differ in that the -A version has a salmon and cream cabinet while the -B version is black and grey.

    Battery requirements are an RCA VS064 or Eveready 729 combination pack which supplies 1.5V and 90V for the tuner and amplifier and 4 D cells which operate the phono motor. An external 120V adapter (RCA model RK-198) is available which supplies voltages in place of all batteries via a 7 pin connector on the back of the set.

    The radio is a conventional superheterodyne circuit using battery tubes. The unit is designed so that when the record player is to be used, the RF and IF tubes are powered off and only the audio circuits are still active in order to conserve battery life. The player is a single stack manually operated affair and provision is made to store records on the inside of the lid. 

    Please note that the schematic indicates that the record player is a changer, however, this model is not a changer.
