I am buying this for a Hammond AO-29 amplifier. There are three different versions of the 12au7 from jj. Does anyone know what the difference?

This is the long plate version of JJ's regular 12AU7. This version has a fuller sound.
For a stereo preamp, are the triode sections of each tube measured against one another and matched? Is it possible to get one pair where the triode sections of one tube match the other?

This is not a service we currently offer. The TAD 12AU7 will have balanced triodes. Do a search for SKU: T-12AU7A-TAD.
