| Mode | Plate V | Gm (µmhos) | Rp (Ω) | µ | Plate mA |
|---|---|---|---|---|---|
| CLASS A AMPLIFIER (90V) | 90 V | 1100 | 1000000 | 1100 | 1.2 mA |
| CLASS A AMPLIFIER (250V) | 250 V | 1400 | 15000000 | 2000 | 2 mA |
| RESISTANCE COUPLED A-F VOLTAGE AMPLIFIER | 250 V | — | 250000 | 100 |
Application Notes
The DC resistance in the grid circuit should not exceed 1.0 Megohm. Potential difference between heater and cathode should be kept as low as possible.
