Typical Operation
| Mode | Plate V | Gm (µmhos) | Rp (Ω) | µ | Plate mA |
|---|---|---|---|---|---|
| Single-phase full-wave (2 valves) | 3500 V | — | — | — | 2500 mA |
| Single-phase bridge (4 valves) | 7100 V | — | — | — | 2500 mA |
| Three-phase half-wave (3 valves) | 4100 V | — | — | — |
Application Notes
When quadrature operation is used, the filament voltage (pin 4 with respect to pin 2) should be crossing zero from positive towards negative when the anode voltage is at the peak of the positive half cycle. When quadrature operation is not practicable filament pin 4 should be positive when the anode is positive.
