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

depends on who is doing the claiming and the selling

reputable and truly dedicated tube sellers will screen and test the tubes themselves, not just rely on the factory in china, whose work can often be inconsistent and suspect

and i hope you realize these golden lion tubes are NOT the original British tubes, these are China made copies, they just bought the brand name... absolutely nothing to do with the original genalex on which the brand and reputation was built
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) :-)
