Up for sale is a vintage GE (General Electric) 12AT7 dual-triode tube widely used as a preamplifier, phase inverter, or reverb driver in vintage Fender guitar amplifiers and high-fidelity audio equipment. Excellent for restoring original tone and reliability to your setup. It appears to be unused, in original box, but I cannot verify.
