12AT7/ECC81
The 12AT7 is a medium gain dual triode used in guitar amplifiers and hi-fi circuits. It has the same pinout as the 12AX7 but a gain of 60 instead of 100, higher transconductance, and it can provide more plate current than a 12AX7. The 12AT7 is often used for phase inverters, line drivers and reverb tank drive circuits.
Equivalents to the 12AT7 include ECC81, ECC801, CV4024, and 6201.
