  • Notes

  • The 362 Valve Co. "Class B" Unit & Speaker is a compact and efficient combination of a precisely matched Class B amplification unit and a high-quality permanent magnet moving coil speaker. This unit comes complete with a 362 Class B valve and requires minimal setup, needing only four-wire connections to convert a battery-powered radio set to Class B amplification.

    The Class B amplification provides significantly increased volume and improved sound quality while consuming very little additional H.T. (High Tension) current. This unit offers performance comparable to speaker units that cost twice as much.
    Priced at 50 shillings.

    Also available as the 362 Kit which includes all necessary components to construct a properly matched Class B adaptor:

    • Class B valve
    • 7-pin valve holder
    • Input transformer
    • Output transformer
    • Detailed instructions

    The kit is priced at 28 shillings and 6 pence.
