    Similar cabinet to the AC model FR10, and based on FR10 chassis but with B7G minature valves and corresponding changes to circuit.

    HT +117 108 & 10.5 volts

    LT 2 volt

    The 2V is not a mistake, even though it's 1.4V tubes/valves. The 2V Lead Acid was much cheaper to charge than buying drycells and could be charged at the local cycle shop, radio shop or garage.
