So I plugged in for about 10 seconds and all was fine, then I started adjusting the treble and then the sound just completely went out as if it wasn't even on. The other channel works just fine too. Now, I'm no amp expert so any help would be greatly appreciated. Did I blow out a tube? They're not even 5 month's old, but maybe that doesn't mean anything.

Thanks guys and gals.
