Automatic Radio-Gramophone 1201

MW/LW AC-powered radiogram with push-pull output and twin speakers.

Garrard 78rpm autochanger.

This new radio-gramophone is certainly a connoisseur's instrument, for it has been produced by the Radio Gramophone Development Company with the very highest standard of quality in design.

This magnificent instrument is in two separate sections. The radio side comprises a seven-valve receiver of the latest type, while the second section below is a four-valve amplifier, with a single-valve mains rectifier. Two loudspeakers are fitted, of the moving-coil type; the output, at maximum, is enough for a small hall.

The exterior finish and general workmanship of the model 1201 are excellent. An automatic record changer and a special pick-up of R.G.D. design are fitted, and the control of the set, on radio and gramophone, is everything that could be desired. Technical listeners will be interested in the specification of the radio side, which comprises a variable-mu high-frequency stage, first detector, triode oscillator, variable-mu screen-grid intermediate-frequency stage, double diode triode second detector, triode inter-station noise-suppressor and two low -frequency amplifiers. The push-pull output comprises Mazda PP3/250's. These two valves give an output of about six watts and the quality over the whole range from a minimum to maximum volume is excellent.
