"For example I have Sovtek 6L6WXT+ and E-H 6L6EH tubes that appear identical, weld for weld. Maybe they have different grids and cathodes that cannot be seen and maybe they differ electrically."You can't go by looks alone. A 12AU7 RCA looks just like a 12AX7 RCA. Which looks just like an RCA 6EU7. RFT 12AX7, 12AT7, and 12AU7 all use the same plate, they look identical. Late production Sylvania/Philips 7581A, 6L6GC, and 6L6WGB all use the same plate structure. 6GU7 RCAs and 12BH7 RCAs look identical. There's many more examples.
Materials used, spacing, cathode chemistry, there's lots of variables you can't see with the naked eye.
