PS Vane tubes ?

The Genalex Silver are Chinese tubes like I've described.
It's kind of a Mullard design yes. Just like the Ruby 12AX7AC7HG and the Tubestore Preferred I mentioned.

Ruby is just a vendor. They put their label on different Chinese, Russian and Slovakian tubes.
The more popular Ruby 12AX7 are probably the JJ ECC83S and Shuguang 12AX7B ones. The latter was labeled as Ruby 12AX7AC5HG (and HG+ for the V1 selected ones).

It was just the traditional Chinese plates tubes. Here's the one

I'm not Dave Friedman so I can't send you one of his amps.

Dang it ! lol

I'd recommend giving the JJ ECC83MG a try too - it's a nice tube, plates are a bit shorter than the ones of the ECC803S but longer than the ECC83S.

Gonna give the MG a try, thanks !

Thanks!
That's a Chinese 12AX7 - the same that was sold as the Ruby 12AX7AC7HG or the Tubestore Preferred Series.
The Russian Reflector company bought a big bulk of these from China when another customer rejected them.

Have a few Chinese 13ax7s, not noisy, not microphinic. Have no real complaints with them
