Genalex Gold Lion 12AX7 - different grades?

@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.

I have, the a few of the original GLs 1960s stuff, a quad of KT77 and KT88s, I have a set of KT77s russian made current matched (12). They sound a lot like the original GL. I don’t like the sound, it’s darker, lacks luster, so to speak. Some folks seem to like that sound, I don’t! I have GLs 12AX7s, 12AU7s, and EL84s, not a one of them are anything to write home about. NOS, New, or otherwise.

A valve that is really stepping up to the plate is PSVANE, I picked up 12AX7s and 12AU7s, VERY good valves, as close to the older Tellies or RCA black plate as I can find, Excellent valves... THAT is the sound I like.

It is VERY tubie, by todays standards.. YES TUBIE. A little bloat in the middle and silky smooth on the top, not brash, or all metal sounding, no bass because I don’t use valve units for bass on the power side.

In a preamp they are just the bomb, great bottom to top. Kind of a frown, if we were looking at an Graphic EQ.

Hello from another Manley Snapper user. Just wondering if you did get around to trying the Gold Lion KT77 in your Snappers? if so, what were the results. I have mine running with Tung Sol 34B and great as they are I am looking for improvement in bass (with losing the mids or highs) and have read on some forums that KT77 offers better over all sound including better bass. Looking to learn from your experience.

@charan : 
I decided to just go with Manley's advice & just redo the Tung Sol EL34B. Since I retubed both snappers ....one of the tubes on the left is intermittent noisy , tap it , fine 😑. I think I'll try the Gold Lion's next up. 

@tommypenngotti. Thanks for your update. Will keep an eye out for your experience with the Gold Lion KT77
