Notes

The internal shield is connected to the pentode cathode and grid No.3 (pin 6). The cathode circuit impedance should be kept as low as possible to minimize cross-coupling between sections.
The pentode section has a second set of operating conditions at low plate voltage (Va=65V, Vs=150V) with Ia=46mA, Is=15mA — intended for video output service.
Heater warm-up time is approximately 11 seconds. In series-string operation the heater current rating is 0.450A at 6.3V.
