  • Notes

  • Mains mode only AC (not DC). Price 17 1/2 gns, including tax (£18.38 decimal).

    Upright model with slow motion tuning and Ferrite Rod aerial.

    Five way (mains) LW MW OFF MW LW (battery)  layout swtich.

    LW 1052 to 2000m

    MW 187 to 550m

    Uses combo L5550 battery (Ever Ready B148), HT 9.3mA, LT 25.9mA 

    Mains 8 VA, (mains LT should be adjusted to 23.8mA +/- 2% with AC mains voltage at centre of range, including meter error, eg 225 on 220 to 230V tap). Transformer  isolated chassis, but LT derived from 90V HT. Additional series resistor added between V4 and V2 on mains results in higher LT voltage reading than you would expect as with Lady Anne CN430 attaché case version (similar circuit with mains and same battery).

    Panel layout is suggestive of the Lady Anne in an upright case with geared tuning.
