Here's a good tube source in the USA.
_http://www.tubesandmore.com
There are only about 5 or 6 factories making tubes these days. 1 in Yugoslavia, 2 in Russia, at least 1 in China, and a few more I can't remember. When you see some Ruby Red "Groove Tube" in a music store, it came from one of the above sources.
I've been buying tubes from tubesandmore for over eight years and just thought I'd let you know they are "legit" so you don't have to worry about giving them your credit card info etc.
