5751 JJ Preamp Tube

The 5751 from JJ Electronics is a double triode can be used in most 12AX7 circuits to achieve more headroom. It has a lower gain than the standard 12AX7. Similar to the 12AU7 these tubes are great for controlling gain in your amp.

The 5751 is a drop in replacement any 12AX7 circuit and was designed as a stronger high mu, dual triode tube and while it has similar specifications as a 12AX7 it has 30% reduction in the gain and is another great way to tame a distortion stage and shape the tone your amp produces. Designed with short plates, these tubes have great compression and harmonic complexity and are perfectly suited for creating tight midrange tones with warmer high end response.
