12at7 with 12ax7 tubes

A follow up with the 12at7 tubes: I have a pair of Tungsram tubes that I brought for a VTL pre that was sold. I kept the tubes so hence the post. Installed them this afternoon (replaced a pair of Tungsol) and WOW. No difference in gain to my ears and the sonics of the Tungsrams walk all over the Tungsols. The battle of the T's should be the title of this post. : ) Thanks again to all.

Happy listening!!

This is good to know.
I have an amp coming that uses 12AX7s. I do have some better 12AT7s that I'll investigate dropping in. I didn't know that ATs and AXs were interchangeable. (I do have 5751s coming as well).

Sebrof let us know what you think when you get them installed.

Just got the amp and tubes yesterday. I'm breaking in the power tubes, the 5751, and amp before I start rolling. I'll try to remember to post back in a few days.
