Agon member @johnss mentioned one other tube above that I heard a year ago in a tube replacement situation on a friend's amp. As it turned out he was running the wrong spec tubes for the amp, TS KT150s, actually. Great tube, wrong amp for them.
Went back to KT88s. The repair person, ex-dealer, chose a well-matched quad of PSVANE KT88 tubes for the replacement. We heard the before and after results. It was a notable difference. The right tube for the amp, or maybe lucky synergy. Still running after a year so far. Maybe another one to add to your research list, fwiw.
