Threat of fire from audio equipment


Just read Art Dudley's new piece in Stereophile, and found myself becoming all sorts of worried. For many, many years now, I've left solid state equipment powered on -- except during thunderstorms or when heading away from home for extended periods. Now, I'm rethinking this practice.

See Mr. Dudley's article here:

My questions:

Is what happened to him the rarest of things, like someone's being struck by lightning? Is putting an amp (or another piece) into standby mode any better than leaving it on -- when it comes to preventing fire, that is -- or can a unit in standby mode burst into flames just like one that's powered on fully? Do others worry about fire? As much as I appreciate a fully warmed-up system, if fire is a legitimate concern, I'll routinely switch things off when I'm not around and listening. Or about to listen.

I'd love to learn what others -- especially those who understand engineering and electricity -- do with their equipment.

Thanks very much.

Wellll. lightning can do crazy things, with the unit on or off.
But a) it should be fused so that the fiuse protects you. I under-fused all my products - they would not pas full power on a test bench the way we shipped them. But in real life, you can barely get 10% out on a steady state basis - the peak to average ratio in audio is like 20:1
Sadly i still get calls "my amp wont turn on". me: did oyu check the fuse?"Why did it blow a fuse?" me: to save its ass and maybe yoursok, i didn't quite say that.

Next, never put a product that is open with vent holes on a flammable surface. Put it on a piece of metal, a block of wood..... (its not that flammable) - but NOT carpet.
If the unit has standby - do it. Mine did - only the low power circuits were on 24 x 7. The rest warmed up in 30-60 minutes depending on how fussy one is.
YMMV
