Application Notes
When this valve is operated with the anodes in parallel, a resistance of not less than 50 ohms should be connected in series with each anode in order that each shall carry its proper share of the load. The resistances should be increased to 100 ohms each if the load is less than 75 per cent of the maximum current rating of the valve.
