Genalex Gold Lion 12AX7 - different grades?

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

disclosure I am only a customer

rodman99 is correct

i should restate what i posted earlier

genalex gold lion reissues are russian tubes, the brand is owned now by new sensor, and the tubes are made in the saratov russian plant... quality is quite good, probably the best currently made tube

it is the golden dragons, which are chinese tubes, made by shuguang... the chinese have improved their quality quite a bit since the bad old days of the 2000's and early 2010's... but russian tubes are still better in general

@jjss49 thanks for the update on the Shuguang QC improvement. I had tried there KT-88's years ago and really enjoyed them but there were to many failures within the first few months to justify continued use.
