Why aren't new vacuum tubes as good as old ones?

LOL! Sorry....every time I read Carson City I can't help thinking of the movie Con Air and Cyrus the Virus. LOL!

USA! USA! USA! USA!

I have high hopes for this venture. It sounds like they will be able to make tubes that are even better than the NOS classics.

Me too Atmasphere. While I find the sound of the newer tubes in some cases to EXCEED any of the NOS tubes I've tried they just don't hold up for whatever the reason(s). I would LOVE to purchase tubes that are made in the US and would hope they exceed the performance of the NOS but retain the quality and longetivity that the Chinese tubes in particular are seemingly lacking.

When you guys talk about "better" that include sound quality?.

Yes and durability. One of the reason I read is some raw materials are banned due to environmental reasons so they can't produce the same quality tube.

Atmasphere, what's the name of the tube manufacturer in NV?

Hi Atmasphere, I am very interested with your finding of this new tube company in carson city, NV,, I believe if they have less dies, the tube will be made to last longer, and maybe be as good as ww 2 nos tubes, you said they were going to make the 12A-series tubes, I would be grateful if you could E-mail me information on them with pricing, if they have prices yet?, you can E-mail me thru audiogon here, thankyou Ralph.
