Uh-oh. Counterpoint time.
I've owned ONE fully tube device, an Ampeg SVP-Pro. It can work fine, and when it does, it sounds lovely. It has never made it through a whole gig, no matter how short.
It just cuts out, and won't come back. It's been looked at 3 times, and no-one can fix it.
YES! Of course it's out of warranty.
And it always brings its buddy, captain 50hz hum to the party.
It has had a second full set of valves, supposedly "good" ones, yet still it happens.

Mine did this too - there's thermal cutout on the transformer (single strand of wire across the top) that might need looking at.
