This British-made Mullard 12AX7A dual-triode preamp tube is a classic choice for valve amplifiers, high-end audio preamps, and recording gear. Featuring original white screen printing with 'MADE IN GREAT BRITAIN' and code '1022 - 501', it delivers the smooth top end, rich midrange, and musical warmth characteristic of classic British tube manufacturing.

Ideal for pre-amplifier stages in guitar amps or audio circuits where low noise, high gain, and reliable performance are required. The tube features clean glass, intact internal plate assembly, and a standard 9-pin mini base.

This tube has been tested on an automated valve tester and verified in 'Good' functional condition.
