Collection of Bekir Yurdakul F. Typically a 12AX7 datwsheet is configured with a high-value plate resistor, k ohms in most guitar amps and k ohms or more in high-fidelity equipment.
The 12AX7 is basically two of the triodes from a 6AV6 – a double diode triode. Vacuum tubes Guitar amplification tubes. 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.
Collection of Ottmar Rollmann D. Different versions of each were designed rcc83 enhanced ruggedness, low microphonicsstability, lifespan, etc.

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

A 12AX7 ‘Shootout ‘ “. In this role it is widely used for the preamplifier input and mid-level stages of audio amplifiers. You will find thousands of tubes or valves with interesting links. In other projects Wikimedia Commons.

Collection of Otto Frosinn D. Collection of Tomasz Szczesniak PL. Erb Analysis by original leaflets. Retrieved from ” https: The 12AX7 was originally intended as replacement for the 6SL7 family of dual-triode amplifier tubes for audio applications. Collection of Tony Smith GB.
The ‘E’ in the European designation classifies this as having a 6. The 12AX7 is the most common member of what eventually became a large family of twin-triode vacuum tubes, manufactured all eecc83 the world, all sharing the same pinout EIA 9A.
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.
In the US a “W” in the designation, as in 12AX7WA, designates the tube as complying with military grade, higher dataheet specifications.
Collection of Stig Comstedt S. Grid bias is most often provided by a cathode resistor. You reach this tube or valve page from a search after clicking the “tubes” tab or by clicking a tube on a radio model page. Collection of Tor Steinnes N.
It has relatively high Miller capacitance, making it unsuitable for radio-frequency use.
