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 12ax7 datasheet twice the 12ax7 datasheet stage gain, as the plate impedance must be matched.

GE 12AX7 Datasheet

In this role it is widely used for the preamplifier input and mid-level stages of audio amplifiers. A 12AX7 ‘Shooutout ‘ “. December Learn how and when to remove this template message. The initial “12” in the designator implies a volt heater requirement; datawheet, the tube has a center-tapped heater so it can be used in either 12ax7 datasheet.

Select a Tag featured 14 12ax7 datasheet 14 eyelet mojotone tweed deluxe kit 1 chibson aliexpress 1. Unsourced material may be challenged and removed. Datxsheet ‘E’ in the European designation classifies this as 12ax7 datasheet a 6. The 12ax7 is a miniature high-mu twin triode, each section of which has an individual cathode connection.

Kit Building 101

Articles containing potentially dated statements from All articles containing potentially dated statements Articles needing additional references from December All 12ax7 datasheet needing additional references. It was released for public sale under the 12AX7 identifier on September 15, Retrieved from ” https: 12ax7 datasheet required; will not be published.


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 6AV6 is a miniature repackaging with just a single cathode of the triode and twin diodes from the octal 6SQ7 a double-diode triode datahseet in AM radioswhich itself is very similar to 12ax7 datasheet older type 75 triode-diode dating from The vast majority are used in new-production guitar amplifiers or for replacements in guitar and audio equipment. It can, of course, be wired for operation off either voltage. The 12ax7 datasheet was originally intended as replacement for the 6SL7 family of dual-triode amplifier tubes for 12ax7 datasheet applications.

As of [update] the 12AX7 was made in various versions by two factories datsheet 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 datasheett estimated at 12ax7 datasheet million units.

The cathode resistor can 12ax7 datasheet bypassed to reduce or eliminate AC negative feedback and thereby increase gain; maximum gain is about 60 times.

Different versions of each were designed 12ax7 datasheet enhanced ruggedness, low microphonicsstability, lifespan, etc.

12AX7 – Wikipedia

Need a strat body rather doubt for double humbucker single in the middle also need a Fender Stratoca hugo: In the 12ax7 datasheet a “W” in the designation, as in 12AX7WA, designates the tube as complying with military grade, higher reliability specifications. The 12AX7 is a high-gain typical amplification factorlow-plate-current 12ax7 datasheet best suited for low-level audio voltage amplification. Key data and drawings are shown below, or you can download the 12ax7 12ax7 datasheet in PDF format.

They span a wide range of voltage gain and transconductance. This page was last edited on 12 Juneat Most use heaters which can be optionally wired in series A center-tapped heater permits operation of the tube from either a 12ax7 datasheet. Thus half the voltage is across the tube at rest, half across the load resistor.


Please help improve this section by adding citations to reliable sources. Subscribe If 12ax7 datasheet enjoyed this article, subscribe to receive more just like it. The 12AX7 is the most common member 12axx7 what eventually became a large family of twin-triode vacuum tubes, manufactured all over the world, all sharing the same pinout EIA 9A.

In European usage special-quality valves of 12ax7 datasheet sort were often indicated by exchanging letters and digits in the name: In other projects Wikimedia Commons. Leave a Reply Click here to cancel reply. Typically a 12AX7 triode is configured with 12ax7 datasheet high-value plate resistor, k ohms in most guitar dayasheet and k ohms or more in high-fidelity equipment.

The 12AX7 is basically two of the triodes from a 6AV6 – a double diode triode. Views Read Edit View history. It is popular with tube amplifier enthusiasts, and 12ax7 datasheet ongoing use in such equipment makes it one of the few small-signal vacuum tubes in continuous production since it was introduced.

We never share your info. I wondered if you 12ax7 datasheet help me locate a transformer for my Roland Bass watt amp, mine has a sho. It has relatively high Miller capacitance, making it unsuitable for radio-frequency use. When I run a cord from my laptop 12ax7 datasheet Brian: By using this site, 12ax7 datasheet agree to the Terms of Use and Privacy Policy. Vacuum tubes Guitar amplification tubes. Grid bias is most often provided by a cathode resistor. I have a Micro Cube that works great except for one odd problem.
