Typical Operation
| Mode | Plate V | Gm (µmhos) | Rp (Ω) | µ | Plate mA |
|---|---|---|---|---|---|
| Sharp Cutoff | 300 V | 9000 | 1000000 | — | 10 mA |
| Remote Cutoff | 300 V | 9000 | 1000000 | — | 10 mA |
Application Notes
The d.c. resistance of the grid input circuit should not exceed 0.25 megohm when the screen voltage is obtained from a fixed source. When a series screen resistor is used with full cathode bias, the d.c. resistance in the grid input circuit may be as high as 0.5 megohm.
