The EF86 is a high gain pentode designed to amplify low-level audio signals. Introduced in the late 1950's, it is used as a preamp in audio equipment and instrument amplifiers. Beginning in the 1950's Mullard was producing hifi amplifiers that used the EF86 as a high-gain input tube and Vox was doing the same in their guitar amplifiers.

We have several EF86 tubes to choose from. Current production by Tung-Sol, JJ Electronics, and Electro Harmonix, as well as various NOS brands. Be sure to read our EF86 review/comparison for help determining which is best for you.
