Is it harmful to my AXE...?

[rolidoc]

last Friday night after using my AXE I forgot to turn it off and noticed this in the morning after 14 hours. Maybe it's not a big problem and it's still working but I wonder if it's harmful to my AXE to let the power on for a long time. Any experience?

More likely to damage semiconductors in the long term repeatedly turning on or off....typically better to leave on, as long as properly ventilated.

I think I read a post about this in the past, and it seems like Cliff chimed in that he leaves them on all the time.

No. I do suggest turning it off at the end of a session to save electricity.
