Groove Tubes EF86

This tube is selected for low microphonics and hum, and for high gain so as to produce a strong signal to noise ratio when placed in critical audio paths. Specially selected for low noise for use in tube mics and recording gear. This tube is a pentode and is not interchangable with a common 12AX7 type tube. This tube is used in some early Vox AC-10, 15, 30/4 amps, Matchless DC-30 amps, some Bad Cat amps, Victoria Sovereign, and the Doctor Z amps: Z-28, Route 66, KT-45, and 6545. EF86 / 6267 tubes made today are very inconsistent. Their transconductance and current capabilities are quite far ranging from tubes of this type from the sixties. GT puts each and every one of these tubes though a battery of tests to ascertain a tube that will stand up to the rigors of a first gain stage position. The first gain stage of the amps above are where these are used, and proper characteristics are critical.
