Need a strat body rather doubt for double humbucker single in the middle also need a Fender Stratoca hugo: Retrieved from ” https: December Learn how and when to remove this template message. It can, of course, be wired for operation off either voltage. This page was last edited on 12 Juneat Popular Recent Comments Archives. It is especially suited for use in resistance-coupled voltage amplifiers, 12ax7 datasheet inverters, multivibrators, and numerous 12ax7 datasheet circuits where high voltage gain is desired.

They span 12ax7 datasheet wide range of voltage gain and transconductance.

Vacuum tubes Guitar amplification tubes. Email required; will 12ax7 datasheet be published. The initial “12” in the designator implies a volt heater requirement; however, the tube has a 12xx7 heater so it can be 12ax7 datasheet in either 6. The 12AX7 was originally intended as replacement for the 6SL7 family of dual-triode amplifier tubes for audio applications. From Wikipedia, the free encyclopedia.

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-Sol 12a7, and other brands 12ax7 datasheet which the firm has acquired trademark rightsone in China Shuguangand one in Slovakia JJ Electronicfor a total annual production estimated at two million units.


12ax7 datasheet half the voltage is across the tube at rest, half across the load resistor. The 12AX7 is the most common member of what eventually became daasheet large family of twin-triode vacuum tubes, manufactured all over the world, all sharing the same pinout EIA 9A. In this role 12ax7 datasheet is widely used for the preamplifier input and mid-level stages 12ax7 datasheet audio amplifiers. Different versions of datasbeet were designed for enhanced ruggedness, low microphonicsstability, lifespan, etc.

Key data and drawings are shown below, or you can download the 12ax7 Datasheet in PDF format. Comments 3 Trackback URL. I wondered if you could help me locate a 12ax7 datasheet for my Roland Bass watt amp, mine has a sho. If the cathode resistor is unbypassed, negative feedback is introduced and each half of a 12AX7 provides a typical voltage gain of datashdet 30; the amplification factor is basically twice the maximum 12ax7 datasheet gain, as the plate impedance must be matched.

12AX7 – Wikipedia

I have a Micro Cube that works great except 12ax7 datasheet one odd problem. The ‘E’ in the European designation classifies this as having a 6.

The 12AX7 is a high-gain typical amplification factorlow-plate-current triode best suited for low-level audio voltage amplification.

It has relatively high Miller 12ax7 datasheet, making it unsuitable for radio-frequency use. The 12ax7 is a miniature high-mu twin triode, datazheet section of which has an individual cathode connection. The cathode resistor can 12ax7 datasheet bypassed to reduce or eliminate AC negative datashret and thereby increase gain; maximum gain is about 60 times. It was released for public sale under the 12AX7 identifier 12ax7 datasheet September 15, In the US a “W” in the designation, as in 12AX7WA, designates the tube as complying with military grade, higher reliability specifications.

A center-tapped heater permits operation of the tube from either a 6. We never share your info. Typically a 12AX7 triode 12ax7 datasheet configured with a high-value plate resistor, k ohms in most guitar amps 12ax7 datasheet k ohms or more in high-fidelity equipment.


Most use heaters which can be optionally wired in series Please help improve this section by adding citations to 12ax7 datasheet sources. Grid bias is most often provided by a cathode resistor.
