Erb Analysis by original leaflets. Different versions of each were designed for enhanced ruggedness, ecf83 microphonicsstability, lifespan, etc. The cathode resistor can be bypassed to reduce or eliminate AC negative feedback and thereby increase gain; maximum gain is about 60 times.
You even can look up radio models with a certain tube line up. In European usage special-quality valves of some sort were often indicated by exchanging letters and digits in the name: Dztasheet of Models at Radiomuseum. Collection of Christian Schaufelberger CH. Please help improve this section by adding citations to reliable sources. It was released for public sale under the 12AX7 identifier on September 15, Articles containing potentially dated statements from All articles containing potentially dated statements Articles needing additional references from December All articles needing additional references.
In the US a “W” in the designation, as in 12AX7WA, designates the tube as complying with military grade, higher reliability specifications.
Collection of Klemens Rhode D. The 6AV6 is a miniature repackaging with just a single cathode of the triode and twin diodes from the octal 6SQ7 a double-diode triode used in AM radioswhich itself is very similar to the older type 75 triode-diode dating from The 12AX7 was originally intended as replacement for the 6SL7 family of dual-triode amplifier tubes for audio applications.
RTT Franzis Collection of Carlo La Perna I. 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 Stig Comstedt S. 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 Shuguangand one in Slovakia JJ Electronicfor a total annual production estimated at two million units.

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, daatsheet the plate impedance must be matched. Thus half the voltage is across the tube at rest, half across the load resistor.
It has relatively high Miller capacitance, making it unsuitable for radio-frequency use.
