  • Notes

  • Combined Grid Bias (GB) and "B" battery (HT).

    Two Grid taps (-10.5 and ?) and 23 HT taps on the 84 off  B size (IEC R25) (Ever Ready U10) HT cells, thus HT portion is 126V

    Size 13 columns x 7 row layout (HT is definitely 12 x7 layout), thus 1st column is Grid bias.

    Very early sets had no HT feed resitors (or very few) so each screen gride or anode used a separate tap. Also the same pack may have been used on different models needing 126V on output stage HT but different taps for other stages

    Weight based on Winner 120 (identical style construction but 11 less cells).
