  • Notes

  • Mit original HMV-Plattenspieler zum Ausklappen, Geschwindigkeiten: 33, 45, 78 rpm.

    The HMV record player unfolds from the rear. Speeds 33.3, 45 & 78 rpm.

    Mains supply via a side mounted 3 pin connector (Earth is centre pin and required). While there is a transformer and player chassis is earthed, the radio chassis connects to one mains wire and the transformer provides no isolation as it's just an auto-transformer for filament series chain. The HT uses "dropper" resistors to U142/U107 direct from mains "live".

    Early production used valve/tube types X109, W107, DH107, N108, U107. (all B7G 100 mA except X109, rather than listed Rimlock B8A  100mA types)

    The Export version 5323 replaces LW with a 2nd SW band
