    The "B" battery is used to provide the plate voltage. It is sometimes colloquially referred to as a "dry battery" (although there is no reason why a "wet" battery of suitable voltage could not be utilised for the purpose). The filament is primarily a heat source and therefore the "A" battery supplies significant current and rapidly discharges ...

    There was a Motorola 12-volt car radio tube compliment as a Motorola TO-3 "2N-176" Power Transistor. Tung-Sol identified a device as "TS176" as a coincidence or intentionally, because both also had a Baby-Blue color on the finished material. The inventory lists indicated this product for a few years after the introduction. [44]
