The vast majority are used in new-production guitar amplifiers or for replacements in guitar and audio equipment.

Views Read Edit View history. From Wikipedia, the free encyclopedia. Erb Analysis by original leaflets. Collection of Karlheinz Fischer D. December Learn how and when to remove this template message. 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. RTT Franzis Typically a 12AX7 triode is configured with a high-value plate resistor, k ohms in most guitar amps and k ohms or more in high-fidelity equipment.


This page was last edited on 15 Decemberat Quantity of Models at Radiomuseum. Collection of Giorgio Busletta I. In this role it is widely used for the preamplifier input and mid-level stages of audio amplifiers.

Most use heaters which can be optionally wired in series Collection of Christian Schaufelberger CH.

12AX7 – Wikipedia

Collection of Trev Levick D. Collection of Tomasz Szczesniak PL. The 12AX7 was originally intended as replacement for the 6SL7 family of dual-triode amplifier tubes for audio applications. A 12AX7 ‘Shootout ‘ “.

The 12AX7 is basically two of the triodes from a 6AV6 – a double diode triode. Collection of Werner Braun D.

The ‘E’ in the European designation classifies this as having a 6. 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.


Collection of Otto Frosinn D. Collection of Roland Biesler D.

It has relatively high Miller capacitance, making it unsuitable for radio-frequency use. Collection of Patrice Zeissloff F. Collection of Jacky Parmentier F.

You even can look up radio models with a certain tube line up.

Collection of Reinhard Riek D. The cathode resistor can be bypassed to reduce or eliminate AC negative feedback and thereby increase gain; maximum gain is about 60 times. Collection of Heinz Schmidt D. Thus half the voltage is across the tube at rest, half across the load resistor. It is popular with tube amplifier enthusiasts, and its ongoing use in such equipment makes it one of the few small-signal vacuum tubes in continuous production since it was introduced.
