Hello,

I have a 12AX7 with a logo I can't recognize.

On the back, it says "Made In GT Britain", but I can't cross-match this symbol to Mullard.

Help?

TIA :)

I Can confirm, Voice of Music, I have about 15-20 of them, A couple NIB. Watch these closley, They had mostly used old Mullards as well as Amperex as suppliers. I have EL84's labeled VM but they are clearly Amperex's.
I also have a couple Amperex 12AX7's labeled VM. Found a cache of them in an estate sale where the guy was doing a weekly radio recording deal with a local radio station. He worked from home and had a lot of great old recording stuff.
