| Content | Matched Pair 5751 = a 12AX7 with a bit less gain and big plus on tone! Low-noise Tube for Best Clean Tone!
The TAD Selected 5751 is our first choice for noticeably improved clarity, smoothness, and a true vintage tone character for most guitar amps! There will still be plenty of gain - so if you own a high-gain preamp that does not have these classic crunch characteristics, the 5751 tube will work wonders. In hi-fi preamps and CD players, the TAD selected 5751 will lower the noise floor and sound smoother and clearer than many 12AX7 tubes.
Especially this low-noise tube is recommended for best clean tone with big bottom, warm midrange and silky top end. Performs great for HiFi too! Replaces any 12AX7A/WA, ECC83, 7025 etc.
NOTE: SRV used a 5751 to improve his clean tone with vintage Fender amps producing that thick and three-dimensional bold tone.

Matching and Selecting Options for Preamp Tubes
Matching in Pairs for preamp tubes means that two tubes show identical gain, hence, four characteristically identical systems.
This matching method includes our Balance-Selection. We highly recommend this matching method for hi-fi systems.

Selected ECC83 for the big & warm clean sounds (great for HiFi too!) and mellow top-end when pushed to overdrive. Our recommendation if you want to emphasize punchy mids. Especially great when pushed into a fat overdrive.
All preamp tubes labeled Premium Selected have passed the following tests:
- Low Noise Test
- Microphonic Test
- Gain Test
- Sonic Tests
- Shock Tests
- Listening Tests
- Balanced Output Test
Premium Selected
We call the tubes SELECTED which have passed above tests and thus qualify as reliable all-round tubes of their type.Typically this is around 30-60% from a batch that receives the SELECTED label from TAD.
For applications in particularly sensitive functions such as V1 or input stage with combo amps, V1 in high-gain amps, tube microphones and phono preamps, we recommend using the respective HIGHGRADE selection
