Smoke on my power amp

I was listening the music with the right speaker wire detached to listen to the left speaker alone. The speaker wire was still attached at the amp side. My preamp does not have the balance knob.
After 20 secs or so, there was a smoke on my power amp.
I quickly turn off the amp.
Once smoke comes, would it be safe to turn it on again? I wonder whether it is permanently damaged.
Is it not safe to listen to the music with the speaker wire detached from one speaker but still attached on the amp side?
My amp is Plinius SA 102.
Any comment?
thx

I brought it to service, and the service tech found a few components got hot, but nothing else. He said those components are not really burnt, and can function OK even after got hot and smoked.
I brought it back home and tested, and indeed it works fine.
Hope that it only burn the paints and did not negatively affect the components.
Thanks all, Al, masaja415, ...

ihcho, I probably missed it, but where was the paint burned, on the capacitor or whatever got hot, on the inside chassis, or the outside chassis?

The tech told me that he saw some power resistors got hot, but they were not burnt. According to him, other parts looked OK.
