The obvious answer would be when it sounds shitty. But here is the thing.
I have a tube amp that I hardly ever play, except for gigs or recording. I turned it on today, and gave it a good thrashing (loud enough and long enough for the power tubes to get a good glow on). Well to make a long story short, the tone sounded to me like I was running it through a compressor and squishing it - at least compared to how I remembered it. The thing is, it has been about 2 months since I played it last, so I don't know for sure if it sounds different, or if just my perception (all I have been using lately is a solid state randall for rehearsals, and amp modelers for "riffing around", and both can be a little harsh on the high end).
So what are the early signs that tubes need replacing?
