  • Notes

  • This 51S Special has a different panel from the 51SD Special DeLuxe

    Operating instructions (see tech.info) show a choice of completely different tube configurations:
    2 x UV201A needs a 6 v storage "A" Battery
    2 x WD12 uses 1.5 v dry "A" Battery
    2 x UV199 requires 3 x 1.5 v (= 4.5 v) dry batteries plus socket adaptors.
    Same is valid for the Cunningham equivalents.

    Later models could also use the following combinations:
    2 x UX199;
    2 x UX201A;
    and for increased output power:
    UX201A and UX112A
    UX201A and UX171A;
    UX199 and UX120;

    Later models have a terminal to connect a "C" bias battery in case of operation with an output tube of increased power: UX112A (max0.2 Watt); UX171A (max.0.7 Watt); UX120 (max.0.11 Watt).
