| Description |
A moulded mounting block was supplied with the tubes. The filament is for 0.8 ampere at 4 volts. The anode operates normally at 2 to 22 volts. With the two ended design the tube has lesser capacitance than normal (single ended) triodes of that time, such working on higher frequencies. These tubes were first manufactured by the predecessor "Radio Lamp" - see company history.
