• Notes

• The Regentone all-electric two-valuer is available only for A.C. mains operation. As voltages and frequencies differ so widely in this country the makers have provided a neat and accessible tapping arrangement so that all voltages between 200 and 250 volts can be used if the set is suitably adapted before the reception is undertaken.

  The standard model is suitable for periodicities between 40 and 100 cycles. There is also a special model for 100-volt mains and for 25-cycle frequencies. No corresponding model is available for D.C. mains or for battery operation.

  Valve Combination.

  As there are only two valves in this set, the circuit combination is naturally limited to a detector and one low-frequency-amplifying valve. The detector is a Mullard 904V, which has a 4-volt indirectly, heated filament. The low-frequency valve, which is, of course, also the output power valve, is a Mullard AC104. These two valves are coupled together by means of a transformer. Ample output volume can be obtained from the local station, sufficient to work a moving-coil loudspeaker.

  As the detector valve is provided with reaction the set is quite sensitive and should be suitable for loud-speaker reproduction up to 50 miles from a regional broadcasting centre.
