I have been using a pair of WE 300B tubes (new production) since 1994! They have seen on-and-off use for about 6 years in a pair of Welborne Laurels, several years use in a pair of Fi mono's, and several years use in an AN Kit-1. All these years, and many thousands of hours use, without ever so much as a belch, burp, or fart. Expensive, but well worth the additional cost.
