Sensibly equivalent¶ to:
The 2C34 transmitting double triode covers the VHF frequency range. The triode can be driven hard and this valve can accept a grid current of 15 mA.
The interesting thing about this exhibit is the neat support sleeve shrunk round it. We have seen apparently identical sleeves on some other WWII valves of American origin. Presumably the sleeve was intended to 'repair' a valve whose base cap was becoming loose but by whom is unknown.
The classic envelope is 42 mm in diameter and, excluding the UX7 base pins, is 110 mm tall.
References: Datasheet Type 2C34 was first introduced in 1938.
