About NOS 12ax7 and 12au7
When you try something likeLorenz 1959 long welded plate o-getter ecc802
Philips 1955 Holland long plate d-getter ecc83
Tungsram 60s silver plate, silver pin double getter support ecc83
Valvo 1955 long plate copper grid foil getter ecc83
Philips 1954 Coppenhagen long welded plate d-getter ecc83
Siemens 60s triple mica silver plate ecc82
Valvo 60s triple mica 6067
....it was not problem to understand what NOS tubes were all about.
Sorry but my advice is to try some of the real ultimate 50s - 60s Euro or American tubes in top audio systems before current tubes.
