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??

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...

Apos Ray 12au7??

Never heard of them, interesting. I'll look them up. I've always exclusively used nos.

@jafox ,

I'm not sure 12bh7's are interchangeable with 12au7's in all applications.

Do you have any insight on this?

@buellrider97 ,

Man, good price!

Yeah, prices have really gone up on the more sought after tubes. Thanks for sharing your experience.

@andynotadam  I just ordered a matched pair of the Apos Ray 12au7s Will try them out in my Rogue Sphinx V3.  Was thinking of trying the Mullard 4003s as well. Not interested in the expense of NOS for this amplifier. Thanks for the rec.

   @mesch, please let me know if you like them. I’ve tried about a dozen different 12AU7’s and just prefer Telefunkens. That being said Tungsram 12 AU7’s and the nos Tesla ecc82’s  ( Not JJ’s ), sound similar to Telefunkens and are considerably less. As far as nos Mullards, you either love em or dislike em, I’m the latter as they throw a veil over the music. I run a paltry Rogue RP-1 with upgraded footers, power cable and nice interconnects. It actually sounds good for having reached its limit. I’ve not played with the Sphinx , but if it’s not too bright the tubes I mentioned would probably be good. Considering it ships with JJ’s pretty much anything will be an improvement. Happy Hunting, Mike B.
