I have a Sylvania green print JHS 12AX7 made in 1961 or 1962 (?) for trade. I bought a matched pair but I only needed one for my MAD Ear+HD.

 

I don't know anything about tubes so here is what the guy who sold me the tube wrote in his ad :

 

very nice pair of vintage Sylvania green print JHS 12AX7 made in 1961 and 1962.
These have top halo getter with copper grid posts and very sturdy grey box plate design.
Very clean tubes, deep low end and crisp top transparent and open sound .
Tested for shorts leaks and dynamic conductance on my tester.
Minimum good= 70 NOS= 120

Tube 1- 114/118
Tube 2- 119/117

 

Since there was no indication on the box I don't know which one is #1 and #2 ... But to me they sound exactly the same.

 

Looking for a nice 12AX7/5751 tube.

 

Thanks !

Keep it. They are not making these any more.
