I just got a dead tube in V3. Two previous tubes became crackling in V3. My amp was playing fine and suddenly there was no sound. I pulled every tube and it was V3! What's strange was that the tube was hotter than the others but of same brightness. There was an earlier thread about V3 eating tubes in a JVM205H. I'm curious to know what's so demanding in V3 that it eats tubes. Maybe I shouldn't use NOS in V3? Any advice welcomed. Thanks.
