Anotaciones

This is a "Domestic Use" mantle radio which would have satisfied most urban users of the era. With 4 transistors in the AF stage driving a push/pull output pair of germanium transistors with a 22 Volt supply into a 15 Ohm speaker without an audio output transformer, the audio output would have been average or above for a Mantle Radio of its era. The Ferrite Rod antenna with 140mm shows that it was not aimed at the DX market and there is only the single tuned RF stage and oscillator before the IF stages. The frequency range is 525 to 1780 kHz.

Interestingly, the case still incorporates the full ventilation from a valve radio of the same era.

All metal parts penetrating the case, including the two screws that secure the chassis to the case, are earthed via the power cord, so this radio would pass modern safety checks unlike many of its contemporaries.

It is a "transition" model with silicon transistors in the RF/IF stages but germanium transistors in the AF/output stages. It still bears the "Little Nipper" designation which the 68-55 drops.

Plastic cabinet colours in Red, Tan & Charcoal.
