Extras ▼

 

The 6R7G double diode triode was designed for radio receiver use. In the classic superhet broadcast receiver such a valve would provide signal and AGC rectification, followed by the first audio amplification.
The 6SR7 has the same rating but is in a single ended metal envelope.
The classic envelope is 36 mm in diameter, and excluding the IO base pins, is 94 mm tall.
References: Datasheet, 1040 & 1043. Type 6R7G was first introduced in 1936.
