Need a 12ax7 datasheet body rather doubt for double humbucker single in the middle also need a Fender Stratoca hugo: Email required; will not be published. The 12AX7 is the most common member of what eventually became a large family of twin-triode vacuum tubes, manufactured all over 12ax7 datasheet world, all sharing the same pinout EIA 9A.

It was released for public sale under the 12AX7 identifier on September 15, The vast majority are used in new-production guitar amplifiers or for replacements in guitar and audio equipment.

Different versions of each were designed 12ax7 datasheet enhanced ruggedness, low microphonicsstability, lifespan, etc. This page was last edited on 12 Juneat A 12AX7 12ax7 datasheet ‘ 12axx7. In the US a “W” in the designation, as in 12AX7WA, designates the tube as complying with military grade, higher reliability specifications.

The cathode resistor can be bypassed to reduce or eliminate AC negative feedback and thereby increase gain; ddatasheet gain is about 60 times. If the 12ax7 datasheet resistor is unbypassed, negative feedback is introduced and each half of a 12AX7 provides a typical voltage gain of about 30; the amplification 12ax7 datasheet is basically twice the maximum stage gain, as the plate datashheet must be matched.

The initial “12” 12ax7 datasheet the designator implies a volt heater requirement; however, the tube has a center-tapped heater so it can be used in either 6.
