Auto Radiogramophone 1046G

With the  1046G Auto Radiogramophone, there seems little doubt that it will worthily uphold the pre-war RGD reputation for high-quality radiogramophones. The radio chassis is of unusually clean design and all trimmers are readily accessible. Unit construction has been adopted and the RF coil unit and switch, IF.coil unit, etc., can be removed separately for service.

In addition to the usual medium and long wave ranges there are three shortwave ranges covering 13.8 to 52 metres and a split rotor tuning condenser gives band-spread tuning on the short waves.
The frequency changer is preceded by a tuned RF stage and followed by one stage of IF amplification with three degrees of selectivity. The triode section of the double diode triode second detector is used as a pre-amplifier for the gramophone pickup. A " magic eye " tuning indicator is included.
The amplifier and power supply unit comprises a pentode first stage with tone control, a resistance-coupled concertina phase splitter, and two PP3 /250 triodes in push-pull giving 8 watts with less than 3 percent total harmonic distortion.
The loudspeaker is a 12-inch duplex cone, with a frequency response of 40-10,000 c /s.
On the gramophone side, the 78 RPM Garrard record changer is fitted with a new lightweight pickup using a permanent sapphire stylus.

The cabinet of the R.G.D. Model 1046G is of rigid construction to ensure freedom from bass resonance. Unit construction has been adopted in the design of the radio chassis.

The price of the Model  £148 1s plus  £31 13s 4d purchase tax,
