The Apos Ray 12AU7 new production tubes are really terrific and come with a trial and a warranty. They sound better than new production Gold Lion and any of the NOS 12SU7s I have in my stash including Teles, Brimar, Radiotechnique, Mullard and more...
Anyone ever have, use or hear this tube?
I always thought that the pinnacle of the ecc82/12au7 type tube was the Telefunken ecc802s. Even better than the Amperex 7316. But, I recently found out that there is an extra special designation for some ecc802's dubbed the G73R. These are supposed to be unmatched in quality and longevity, said to last 40,000+ hours! Anybody familiar with, heard or own these things??
