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

I think I have seen the online seller's site you are referencing to. Not sure that the grades mean. But I moved from Genalex Gold Lion to Psvane for my 12AU7 requirements. I suggest you reach out to Viva tubes since they have both and find out the "characteristics" before you make a choice. Their prices are fair and shipping is reasonable.

So you know GL 10% matching, is considered matched, I venture a guess and say, 5% is one option, with gold pins, maybe. They are still russian made valves. Nothing fancy like the older GL KT88s.

Second PSVANE does it out of the gate, GOOD valve, 5% or better matching. Not as dark, I don't know how else to explain GL valves, to me they lack the the luster, I like. To tame so to speak..
PSVANE, GOOD Tellies, (really rare any more) RCA black plate, 59-64 or so. For the money, and for the SQ, PSVANE.

Regards
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
