  • The RF stage is bypassed in case of shortwave reception.

    There is a later version of model 651 with a 1K6 instead of a 1B5 and adapted circuit around it.

    Used a 10" speaker with 20kΩ transformer.

    Also available as model 651V (early) with modifications to the filament wiring to permit 6 Volt storage battery operation.

    Radio Trade Annual 1939 & Mingay's IF Index gives IF frequency as 210 kHz but AORSM gives it as 465 kHz.
