Typical Operation
| Mode | Plate V | Gm (µmhos) | Rp (Ω) | µ | Plate mA |
|---|---|---|---|---|---|
| RF Power Amplifier Class-C Telegraphy (3500V) | 3500 V | 20000 | — | 20 | 1800 mA |
| RF Power Amplifier Class-C Telegraphy (4000V) | 4000 V | 20000 | — | 20 | 1600 mA |
| RF Power Amplifier Class-C Telegraphy (5000V) | 5000 V | 20000 | — | 20 |
Application Notes
The grid lead is detachable so that for grounded-grid operation, complete external shielding may be used between plate and filament circuits. Frequencies below 50 Mc. A minimum flow of 120 cubic feet of air per minute must be passed through the plate cooler.
