  • Power Amplifier and Plate Supply

    This unit operates from 230 volt (50 cycle) A.C. and provides plate voltages of 45, 90 and 130 in addition to supplying the proper plate voltage for the UX -171 tube of the power amplifier.

    An outstanding feature of the type 420 is that it has no variable resistance voltage controls to get out of order and cause noisy reception. Voltages in this unit are controlled by fixed resistances tightly sealed from dust and moisture.

    This unit is designed for the UX -213 Rectron rectifier tube and UX -171 power tube in the amplifier. It is contained in a metal case with black crystalline finish. The type 420 may be used to replace "B" batteries with all popular makes and circuits of radio receivers regardless of whether they may be operated by dry cell or storage battery tubes.
