Type 6J7 is a contemporary of the 'Magic Three' and almost as ubiquitous. Although originally designed as a detector its linear characteristic and good internal shielding (cf. 6Q7GT) made it a natural choice for audio. It was for two decades the international standard valve for audio amplifier input stages and audio systems.The Mullard-Philips type EF37A, for many years the standard British low-noise audio pentode, is really a 6J7G under another name. The predecessor valve was the Type 57 and the characteristics are the same.![](../pics/aaq0656a.jpg)
