I've tried an older Grooves Tube 12AX7 that came out of my old Fender guitar amp when I had it completely re-tubed. It was still good, but it didn't do well in my stereo system. You're probably referring to the more recent GT 12AX7M which is supposed to be a Mullard clone. I've read some good things about them, but I think there have been some interruptions in production that have made them hard to find at times. I'm also looking at the Sovtek 12AX7LPS which seem to be easier to find. The other preamp tube in my integrated is the 12AT7 so I haven't really looked into the AU7.

When you try the GTs, I'd appreciate your opinions on them and I'd like to know where you found them. In the meantime, enjoy your holidays. I'm trying to round up all my Christmas music.
