Yes there's a bunch of threads on this topic
Tube Rolling is one
@mace had this one
V & VII high gain
But is it ok to have another?
So I've been running a JAN 12AT7 7WC in V4 ever since the V:90 showed up years ago. Initially Ch 3 felt harsh so out with the Mesa STR SPAx7-A that was in there, this made a big difference to my ears. However this was when the learning curve was steep with the amp. It was the core amp in the studio, but have now transitioned it to my live rig. Much has changed (signal chain, axes, cabs) as it's getting alot more time and focus these days.
It still has the 12AT7 in V4 but now starting to feel like Ch 3 could use a bit more gain and maybe it's time to evaluate a 12AX7 again. Don't want a return to the harshness, so perhaps there is "lower gain" 12AX7 to try? Will admit I'm not a avid tube sniffer and paying premiums for some hyped tubes just hasn't worked out for me in the past. I think @bandit2013 mentioned the JAN 5157 wondering if there are other suggestions?
I've got some JAN – GE USA (83), a few ECC83s and some newer Mesa branded 12ax7s laying around. But it I do go tube shopping wondering what's a good one to look at.
