NOS, generally a bunch of hype, today their are probaly more good tubes being made than there were 25 years ago, I think NOS got it's big boost when the old manufacturers started dying off and the new guys hadn't got up to speed with quality or selection, ie.. 10 years ago you couldn't buy a new 7027, and NOS was the only way to go ( if you could even find a NOS 7027).

Lordathestrings, you ain't Ranting, just telling the truth!

BTW, if anyone is interested, I have a set of Genaflex Gold Lion KT-66's for sale, the most incredible sounding, high quality, British made, NOS big bottle, super duper tone, first $600US takes them home!
