Extras ▼

 

The 6C8G is a double triode. Each section has a separate cathode and the first valve has its grid taken to the top cap. This will confer greater isolation from the anode circuit than for valve two.
Intended for use in radio-gram type domestic equipment, the 6C8G provided audio amplification and phase splitter in one envelope. The final push-pull output stage was thus driven by this single valve.
The classic envelope is 36 mm in diameter and, excluding the IO base pins, is 96 mm tall.
