The 12AX7 is basically two of the triodes from a 6AV6 – a double diode triode. Terry, not sure if he replied to you, but contact Jim Sharkey at Junksville Guitars and he’ll give y Gary: Key data and drawings are shown below, or you can download the 12ax7 Datasheet in PDF format. How do I go about purchasing the Grizzly H guitar kit giorgos: The vast majority are used in new-production guitar amplifiers or for replacements in guitar and audio equipment.

It is especially suited for use in resistance-coupled voltage amplifiers, phase inverters, multivibrators, and numerous industrial-control circuits where high voltage gain is desired. The 12AX7 was originally intended as replacement for the 6SL7 family of dual-triode amplifier tubes for audio applications.

Please help improve this section by adding citations to reliable sources. The cathode resistor can be bypassed to reduce or eliminate AC negative feedback and thereby increase gain; maximum gain is about 60 times.

From Wikipedia, the free encyclopedia. It can, of course, be wired for operation off either voltage. All information is deemed reliable but not guaranteed. Grid bias is most often provided by a cathode resistor.

Comments 3 Trackback URL. Views Read Dataaheet View history. If the cathode resistor is unbypassed, negative feedback is introduced and each half of a 12AX7 provides a typical voltage gain of about 30; the amplification factor is basically twice the maximum stage gain, as the plate impedance must be matched.
