These are all pin compatible 12at7 with one another, the only differences being the gain vs factor of each tube. The 12AX7 family of dual- triode preamp tubes consists of the 12AX7 12AY7, 12AT7, 5751 12AV7 & 12AU7. 12AU7 Vs 12au7 12AX7 Discussion in ' The.

I know that my CAT pre Mk1 12at7 version 12ax7 datasheet used vs to have 12AU7 but the design now has 6922, which are much quieter. Today I substituted the JJ datasheet 12AT7 in the preamp for 12ay7 the Tung- sol 12AX7 datasheet preamp tubes in V1, V4. I had concerns would this make the pow. 12at7 This represents a huge gain factor change from 100 on the 12AX7 to 60 on the 12AT7. Consider a 12AY7.

If your pre has a 12AU7 in it, someone probably wanted less gain and substituted it in place of the 12AX7. In general, I prefer the sound and performance of new old stock tubes. 12AXAX7A Whats the difference. Did You check out that Tube Data Sheet Jon?

It' s pretty handy for reference. I read so much on here about NOS vs CP and. I think that the 12AX7 might the least microphonic whereas the 12AU7 & 12AT7 are more.
