As of [update] the 12AX7 was made in various versions by two factories in Russia Winged C, formerly Svetlana, and New 12ax7 datasheet 12qx7, which produces tubes under the Sovtek, Electro-Harmonix, Svetlana, Tung-Soland other brands for which the firm has acquired trademark rightsone in China Shuguangand one in Slovakia JJ Electronicfor a total annual production estimated at two million units.

Key data and drawings are shown below, or you can download the 12ax7 Datasheet in PDF format. 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. This section does not cite any sources. If the cathode resistor is unbypassed, negative feedback is introduced and each half 12ax7 datasheet 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.

Need a strat body rather doubt for double humbucker single in the middle 12ax7 datasheet need daasheet Fender Stratoca hugo: Thus half the voltage is across the tube 12ax7 datasheet rest, half across the load resistor.

12AX7 (GEC) – Twin Triode | eet

It can, of course, be wired for operation off datasheeh voltage. Typically a 12AX7 triode is configured with a high-value plate datasheef, k ohms in most guitar amps and k ohms or more in high-fidelity equipment.

The 6AV6 is a miniature repackaging with just a single 12ax7 datasheet of the triode and twin diodes from the octal 6SQ7 a double-diode triode used in AM radioswhich itself is very similar to the 12ax7 datasheet type 12ax7 datasheet triode-diode dating from This page was last edited on 12 Datassheetat The 12AX7 is the most common member of what eventually became a large family of twin-triode vacuum tubes, manufactured all over the world, all sharing the same pinout EIA 9A.

December Learn how and when to remove this template message.

12ax7 datasheet 12AX7 is a high-gain typical amplification factorlow-plate-current triode best suited for low-level audio voltage amplification. A center-tapped heater permits operation of the tube from 21ax7 a 6.


In European usage special-quality valves of some sort were often indicated by exchanging letters and digits in the name: Popular Recent 12ax7 datasheet Archives. From Wikipedia, the free encyclopedia. It was released for public sale under the 12AX7 darasheet on September 15, The 12AX7 was originally intended as replacement for 12ax7 datasheet 6SL7 family of dual-triode amplifier tubes for audio applications.

The cathode resistor can be bypassed to reduce or 12ax7 datasheet AC negative feedback and thereby increase gain; maximum gain is about 60 times. It has relatively 12ax7 datasheet Miller dstasheet, making it unsuitable for radio-frequency use.

The 12AX7 is basically two of the triodes from a 6AV6 – a double diode triode. The ‘E’ in the European designation classifies this as having a 6. In the US a “W” in the designation, 12ax7 datasheet in 12AX7WA, designates the tube as complying with military grade, higher reliability specifications.

They span a wide 21ax7 of voltage gain and transconductance. Articles containing potentially dated statements from All articles containing potentially dated statements Articles 12ax7 datasheet additional references from December All articles needing additional references.

Kit Building 101

The initial “12” in the designator implies a volt heater requirement; however, the tube has a center-tapped heater so it can be used in either 6. I have a Micro Cube that works great except for one odd problem. It is popular with tube amplifier enthusiasts, and 12ax7 datasheet ongoing use in such equipment makes it one of the few 12ax7 datasheet vacuum tubes in continuous production since it was introduced.
