How do you konw when your tubes are out?

[rnp614]

I tried to play some music this morning and I got no sound! I switched to my XBOX and to get sound I had to turn the volume way up (this is on an AE:S).

Are my tubes gone?

More details man, slow down, and lay it all out, what you have, what's connected to what, etc.

Replaced tubes and it looks like the 6x4 was worn way out...while I was in there I replaced all the tubes.

How long do they need to be used before wearing in completely? Or is that not a factor here.
