  Why do old tubes sound better than current tubes?
just wondering, is there something in the design, materials, or fabrication that makes old tubes sound better than those being currently produced?

it seems nearly universally held that old tubes are superior sounding to those made today - is there something specific about the old tubes that make then sound better?

I think the tide is turning a little. The Genelex/Gold Lion reissues (Russian), for instance, are gaining real respect. I've personally replaced "Holy Grail" Mullard xf1 EL34s with Genelex KT77s because the new tubes sound quite a bit better in my amps. And the Sovtec 12AX7LPS is a winner. The reputation of many of the old tubes is, IMHO, a combination of performance and mystique/nostalgia. We're paying a lot for the latter.
