JJ 5751 Preamp Tube


This 5751 is a drop-in replacement for any 12AX7. The 5751 was designed as a "ruggedized" high mu, dual triode tube with similar specifications as a 12AX7. However, with 30% reduced gain, the 5751 is a fantastic way to tame a distortion stage and tone shape an amp. These "short plate" JJ 5751 utilize a "short plate" design. tubes have great compression and harmonic complexity, perfectly suited for creating articulate midrange and warmer high end response.

Price is for a single tube with standard testing.

    I recently bought a PRS Sonzera head and had excessive "hiss" on both channels. I contacted PRS and the rep hinted at using 5751. I did my research and replaced V1 and V2 with 5751's. The hiss was eliminated the gain channel imporved. I also replaced V1 with a 5751 in my Fender Deville to help the volume sensitivity. It worked. The Deville tube change was subtle, but I could hear a difference which I preferred. For the nominal price, you can't go wrong to try it for your application...........

    I've used this as a 'lower gain' V1 in guitar amps. They work great in that application. Very clean sounding tube with little coloration as V1.
