  • Notes
  • 91 x Zinc Carbon cells giving 136.5V, tapped for 124.5 HT and -12V GB (Grid Bias)

    Connection is by a socket at each end and flying leads with small plugs for + and - or various taps. None of this series use layer cells / "Biscuits", all use separate cells with connection wiring.

    Equivalents:

    • Ever Ready Portable 75
    • Others: Drydex H1107, Oldham K634, 1264

    On the "Winner" and "Portable" series the low voltage is a GB (Grid Bias) tap, not an actual LT (Low Tension filament) cell(s). Though some used with "All Dry" sets from 1939 (e.g. Portable 61) the LT would usually have been rechargeable Lead Acid 2V cell
