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.
