Typical Operation
| Mode | Plate V | Gm (µmhos) | Rp (Ω) | µ | Plate mA |
|---|---|---|---|---|---|
| Television Vision Amplifier Service (12.5kW sync output) | 13000 V | — | — | — | 3000 mA |
| Television Sound Amplifier Service (2.5kW output) | 13000 V | — | — | — | 650 mA |

Application Notes
Intended for use as final amplifiers in vision and sound sections of U.H.F. T.V. transmitters and transposers. The modulating anode enables operation at lower power levels in sound transmitters using the same beam voltage as vision amplifiers.
