Notes

The 6Z3 is the renumbered version of the 1-V under the 6-series heater voltage naming convention. Electrically and physically identical.
Half-wave rectifier — two tubes required for full-wave rectification, or four for bridge configuration.
When a filter-input condenser larger than 40 µF is used, additional plate-supply impedance may be required to limit peak plate current to 270 mA.
Heater voltage must not fluctuate beyond 6.3V +/- 10% (max 7.5V) under any operating condition.
