The JJ 5751 vacuum tube is often used in place of a 12AX7. They only have 70% of the gain of a 12AX7 preamp tube, and are often used to quiet down guitar amps that have too much gain. You can learn more about this on our tone tweak info page.

Does what is supposed to

by

I quieted the preamp on my 1993 reissue Sunn T50C with six of these and two Electro Harmonix 12AY7 tubes. The amp is now more articulate and defined. It is also no longer an annoying feedback, squealing machine.
