6SL7 Tubes

The 6SL7 is an octal (8-pin) high-gain twin triode, roughly the octal counterpart of the 12AX7. It's used in the input stages of hi-fi preamps and in vintage amplifier designs. We stock the Tung-Sol 6SL7GT and JJ 6SL7. For a medium-gain octal triode, see the 6SN7, or browse all preamp tubes.
