Tung Sol 5751 Preamp Tube

The Tung Sol 5751 preamp tube is a dual triode tube and a optional replacement for a 12AX7. The Tung Sol 5751 has a gain of about 70-80% of the standard 12AX7.

Did You Know?

If you have any amp that is producing too much gain with 12AX7 preamp tubes, then you could swap these for a lower gain tube such as the 5751 which would help reduce the gain in the amp.

You could go even lower if you wanted to really change your amp’s sound.

If you had an amp that is using a 12AT7, 12AY7 or 12AU7 and it doesn’t produce as much gain as you would like, then putting a 5751 in may “hot rod” it to your liking.
