Genalex Gold Lion 12AX7 - different grades?

Hello all - I’ve been searching for a new set of tubes for my Manley Snappers and have decided to go with the Gold Lion KT77s & 12AX7 . One seller I like has referenced they have different grades "Gold/Platinum" of the 12AX7 , lower noise shelf , microphonics etc....is this possible or sales hype.....as I look around other sellers the 12AX7s all look the same , no classification differences...thanks

Seriously, If you have equipment from Manley Labs, you should contact them directly if you havent already because they have a very large supply of NOS tubes from the 50's 60's 70's. These will sound way better than any new reissued Gold Lion's (this is what all the sites sell). Otherwise try ANDY at Vintage Tube Audio in Michigan. (be prepared to wait a while its worth it) :-)

The Gold Lion re-pops are made in Russia and their reliability- much better than the ____, coming out of China.          Ask any reputable tube monger, for the facts.      Still: +1, far as NOS valves and their sonics, over anything currently manufactured.

Brent Jessee is another reliable NOS tube vendor
Here's a link to his 12ax7 tube page , aside from a listing of brands/models available, you can also read his assessment of how the brands/models soundhttp://www.audiotubes.com/12ax7.htm

Would agree with @milpai, go with the psvanes from vivatubes.

vivia tubes is also carrying the latest vanes, the new art series.. Have just ordered a quad set for myself but have not tried em yet.
