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.

    Perfect for V2 in my DRRI. Lowered the gain just enough to push the amp's power tubes a tad more. The low noise option is wise. Had great service from the Tube Depot.

    Installed this in V1 of my Blues DeVille. Sweetened the tone and in combination with 12DW7 in V2, made the drive/more drive settings less harsh. Service from Tube Depot was 1st class all the way.

    Grabbed one of these for my Splawn Quickrod. I wanted something just a little less powerful for the clean channel. so far so good!!

    I both the 5751 to try as a replacement for 12ax7 is first gain stage. I use small amps in my apartment and wanted lower volume levels. It worked as planned. I haven't put many hours on them yet but they came out of the box without any microphonics.

    I ordered two jj 5751 tubes for my 68 custom deluxe reverb reissue. I got one tube
    for each channel because the amp is noisy and has alot of idle hiss. These tubes are amazing for the price. I payed $4 for the low noise and microphonics test for each tube which was well worth it. These tubes sound warm and have great tone and low noise. I have found my favorite v1 current production tube. I prefer these jj 5751 to the jj 12ax7 smooth highs and tight low end just buy some and try it out for yourself. I'm stoked!

    Got 3 of these (w/ balanced triodes, low noise, matching option) to replace the factory Sovtek 12AX7 in my Crate Vintage Club 20w. Sound amazing and gave me a usable clean tone. 5751 cut the gain by 20% giving you better cleans. Best thing I've done for that amp.

    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.
