...I'm suspicious of current production stock because I'm not convinced today's mfgrs pay as much attention to maintenance of their machinery as mfgrs of 60 years ago did. This includes factors such as the precision of grid winding pitch and alignment of electrodes where that is a factor such as in a beam tetrode. Since such a large proportion of today's production ends up in musical instrument amps where distortion is sorta desirable, this situation probably drives mfg practices.
Some of the nicest sounding tubes I've played with are late 20s/early 30s designs like #45. I speculate that much attention was devoted to inherent linearity in both basic design and in implementation back then because circuits were primative and corrective feedback wasn't in widespread use. Just an opinion/observation w/o numbers or hard facts as backup.
