  • Notes

  • MW 185-555m, LW preset to 1500m BBC Light Programme only.

    Uses T6050 / T0050 / VT50 battery.

    Same case moulding as the slightly earlier valve Vagabond (which has tunable LW), but cream and dark red/plum colour rather than white and bright red.

    Like the Vagabond the handle clicks down and contains a single RF coil Ferrite Rod  (slab) aerial, though the coil design is different.
