Tube 6G8G or Röhre 6G8G ID20737, Double Diode-Pentode, Octal (Int.Octal, IO) K8A, USA 1935 and RF/IF-Stage shown. Radio tubes are valves.
Hi, I'm looking for the pinouts for a Mullard 6G8G vacuum tube. I am restoring an old radio and one of the tubes (or valves to some) is a 6G8. I need to know its pinouts to rewire the radio properly, but I can't find this information in any of my old references and 'net searches have been fruitless. I'd be very greatful if someone could please help me out with this information? Thanks in ...

Pentode- diode- diode; the diodes in this valve were designed for use as the signal detector and automatic gain control rectifier in radio receivers, the remote cut-off pentode section was designed for use as the I.F. amplifier. It could also be used as a resistance coupled audio amplifier following the detector and in reflex circuits could perform both roles. The 6G8G was originally produced ...
Another mica capacitor and resistor connect from the plate of the 6G8G through to ground. (That's off memory, I dont have my annotated circuit diagram on me). This appears to be original because it's a black mica AWA branded cap that matches the rest, and the resistor has the old style colour markings.
This valve has, in one envelope, two diodes and a pentode. It was used in domestic radio receivers. The diodes were used to detect the audio from the IF frequency stage, and to provide a negative DC signal to control the gain of earlier stages (AGC). The pentode was used as an IF amplifier, or the first audio stage. This particular valve is marked D^D, which means it was manufactured for WWII ...
