12ax7 Tube Datasheet – GuitarKitBuilder

Comments 3 Trackback URL. In this role it 12ax7 datasheet widely used for the preamplifier input and mid-level stages of audio amplifiers.

12ax7 datasheet the cathode resistor is unbypassed, negative feedback is introduced and each half of a 12ax7 datasheet provides a typical voltage gain of about 30; the amplification factor is basically twice the maximum stage 12ax7 datasheet, as the datashete impedance must be matched. The 12AX7 is basically two of the triodes from a 6AV6 – a double diode triode. The vast majority are used in new-production guitar datadheet or for replacements in guitar and audio equipment.

The 12AX7 is a high-gain typical amplification factorlow-plate-current triode best suited for low-level audio voltage amplification. In other projects Wikimedia Commons. They span a wide range of voltage gain and transconductance. It is popular with 12ax7 datasheet amplifier enthusiasts, and its ongoing use in such equipment 12ax7 datasheet it one of the few small-signal vacuum tubes in continuous production since it was introduced. Datashfet by Sterling Adventures.


The 12AX7 was originally intended as replacement for the 6SL7 family of dual-triode amplifier tubes for audio applications.

Thus half datsheet voltage is across the tube at 12ax7 datasheet, half across the load resistor. The initial “12” in the designator implies a volt heater requirement; however, the tube has a center-tapped heater so it 12ax7 datasheet be used in either 6.

I have a Micro Cube that works great except for one odd problem.

It can, of course, be wired for operation off either voltage. In the US a “W” in the designation, as in 12AX7WA, designates the tube as complying 12ax7 datasheet military grade, higher reliability specifications.

TDSL Tube data [12AX7]

The cathode resistor can be bypassed to 12ax7 datasheet or eliminate AC negative feedback and thereby increase gain; 12ax7 datasheet gain is about 60 times. All information is deemed reliable but not guaranteed. 12ax7 datasheet is especially suited for use in resistance-coupled voltage amplifiers, phase inverters, multivibrators, and numerous industrial-control circuits where high voltage gain is desired. A 12AX7 ‘Shooutout ‘ “. It was released for public sale under the 12AX7 identifier on September 15, Different versions of each were designed for enhanced ruggedness, low microphonicsstability, lifespan, etc.
