RE: 12AT7-tubes for Preamp and Poweramp :JJ vs Telefunken NOS

Don't overlook Sylvania triple mica 12at7 from the 1950's. They do about 90% + what a Mullard does. It doesn't seem to make much different , to my ears, whether black or grey plates. The cost of Mullard 12at7 are no doubt prohibitive now but Sylvania may still be affordable. You likely can't get them for $2 or $3 a tube anymore but they last a long time and probably less expensive than new era tubes.
