I was right with ya until that last bit. You might want to clarify ??
Preamp tubes often last a very long time. Twenty years is not unusual. The power tubes will wear out more quickly, but one year is [u]much[/u] too soon unless you play very often, very hard, and for a long time each session. My 1977 Ampeg VT-40 applies really nasty voltages, but it's still running very strong on the original Magnavox tubes.
Do the math - that's nearly 30 years! :D
Your problem could be bad tube(s) or it could be something else. You need a [u]good[/u] tech to find the cause quickly, without wasting his time (and [u]your[/u] money) with guesswork. An amp that has been back to the shop 3 times in two years is either a factory Quality Control nightmare, or it's being worked on by an incompetent tech. Or both.
If you're talking about the Traynor YCV-80 in your sig, that should be a bullet-proof amp. Yorkville Sound has a great warranty program ("We fix it even if you break it") based on an excellent design and quality control program. There is something seriously wrong here.[/font]
