Vacuum Tube - 5751, JJ Electronics

$13.75
In stock

The JJ Electronic 5751 is a dual triode that can be used in place of most 12AX7 circuits. The rugged build of this tube and reduced gain (30% less than a 12AX7) can improve headroom and give better control in high gain stages allowing users to more easily dial in sweet spots. The JJ 5751 features a smooth and balanced tone and a detailed response with low noise and low microphonics.

Yes, the P-ST9-600 socket is compatible. Depending on your needs and specifications most 9-pin miniature sockets will work.

If your amp calls for a 12AX7 the 5751 should work as it is a compatible tube.

I use a 5751 in the v1 on a Fender Blues Deluxe ri. And this has made the clean channel warm and Clean.

I'm currently using one of these as V1 in a Peavey Classic 50 and it REALLY nails the Fender cleans and twang and quack, all while working well with my NOS 12AD7 in V2 for lead distortion.
