I may have missed something; wouldn't EIA/RETMA standards dictate that the gm be consistant? I don't mean within 1 micromho, but within a tolerance. I don't think any manufacturer would knowingly make a tube with a lower gm than a 'standard'. Say the mu for the triode is 46; if one manufacturer made theirs with the triode having a mu of 40, rather than label the tube a 6EA8 or a 6KE8, they'd reject it.
I don't know; maybe there is something to it, but I also think there's something you're not telling us. Are these all NOS tubes?
