  • Notes

  • Model UN-45 is specially designed to be used on a bike or moped.

    The UN-45 is 50% Uniframe only, as the chassis is to be made separately. The power is provided from two 6V bike dynamos. One is for filament, the other is connected to a loudspeaker transformer to power the tubes.

    The drawing for the unit reserves space for a small size loudspeaker (diameter 3-4 inches).
