Notes

Pa_max of 3W applies with a grid-cathode resistance not exceeding 10,000 ohms. With max anode dissipation of 2W and max screen dissipation of 0.5W, and a common anode and screen decoupling resistance of not less than 2,200 ohms, the limits are +/-10%.
Ps_max of 1W applies with the same grid-cathode resistance constraint of 10,000 ohms.
Vhk_max of 200V is measured from cathode to the higher-potential heater pin.
Two cathode pins (pins 1 and 3) are provided to minimise lead inductance for RF applications.
Datasheet is marked TENTATIVE (September 1959).
