I'd personally not trust many valve amps to be left on unattended - I've seen
too many go up in smoke. And certainly not a 'budget' valve amp.

Can't say it's ever happened to me, but the potential is there I suppose. Mind,
these days there should be fuses in strategic places. I tend to turn my amp on
in the morning and turn it off at night. With valve rectifiers there's a nice
slow warm up, so not much harm is done turning the amp off and on if you prefer
to do it more frequently. Valves for the most part are not too expensive -
cheaper probably than the batteries a household uses up in the same time span.
So far they have kept their value so spares can even be something of an
investment if you choose wisely and buy at cheap prices.
