  • Notes
  • 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

    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.
