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

Technically, once the blue smoke comes out you need to send it for repair to have the smoke put back in.
@ihcho The Google Photos links you provided in your last post don’t work, at least for members of the public. I’m not sure how or if photos uploaded to Google Photos can be shared publicly.

If you upload the photos to Google Drive, though, and then select/highlight each of them, one of the icons which will appear at the top of the listing will allow you to create a shareable link.

first .... there is nothing wrong to run an amp without speakers or only one channel. but disconnect speaker cables from the amp terminals to prevent  speaker wires   accidental short... most new amps has adequate protection , but vintage ones   do not survive .
so you got 2 possibilities... one is the other ends of speaker cables touched each other . or   just bad luck and amp  got fried with no reason whats so ever . now, can you turn on the amp ?preferably not... for one reason  ...to help a repair man. when he opens the unit and turn it on hopefully  the defective part still smokes  and he can easily determine the problem. but  if you continue to press power button the part eventually would stop smoking and if there is no   easily noticeable burn mark  troubleshooting is more  difficult .
My bad.

I have not turned it on again since the smoke.
I am trying to find which repair shop to send this amp to.
It looks like there is no place working on Plinius amp in Michigan.
Might try Chicago, or send it to Plinius Repairs in CA.

Again, thanks.
