  • Annotazioni

  • General Radio’s redesigned 2-valve standard receiver used a regenerative detector followed by a transformer-coupled audio amplifier. Reaction was adjusted by two movable coils with a reduction gear. Waveband switching excluded part of the aerial coil for short-wave reception. The set’s valves had double filaments: if one failed, the other could be connected. Filament consumption was just over 0.1 amp at 1.4 volts. Valve holders featured spring contacts with a helical phosphor-bronze shock absorber.

    Power was supplied by a Filonator battery and a Radiobats high-tension battery. The Walnut cabinet included a built-in 4-inch metal cone loudspeaker, two edgewise dials (for tuning and reaction), an on-off switch, and a wave-change switch, with magnifying windows for easy dial reading.

    The complete set was delivered & installed for £12.
