The SYLVANIA 12AX7A (ECC83)
is a 9 pin miniature type high-mu twin triode each section of which has an individual cathode connection. The 12AX7A 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 center-tapped heater permits operation of the tube from either a 6.3-volt or a 12.6-volt heater supply. Use of the 12AX7A is advantageous in applications that require low hum and microphonic output. Each triode section exactly similar to 6AV6/12AV6 characteristics.
