The 117Z6 is an American valve designed for American mains voltages. In simple designs and/or mains battery sets, this rectifier can operate without a mains transformer to give 120 Volts for battery eliminator service, or 240 Volts when used in a voltage doubler configuration. This exhibit came from a battery/mains broadcast receiver.
The maximum reservoir capacitor is 40 µF and to limit the peak current the valve must be operated with a minimum of 100 Ohms series resistance.
The end on view of the anode. The working cylinder is of small diameter, the larger width allows for cooling and support.
The anodes in close-up. Stitched folded plates for the anode and the mica supports hold each anode in two places.
The wide glass tube envelope is 28 mm in diameter and, excluding the IO base pins, is 70 mm tall.
Reference: Datasheet. Type 117Z6GT was first introduced in 1940.
