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

In case of TubeAmps!!! Never allow to run it without speakers connected!!!!
In case of the rest, do not shortcut the speaker cable.
Good amps should have safety measures but lets be honest... most up to 5000$ do not have it.
In case of smoke NEVER POWER SUCH EQUIPMENT unless you are professional. Give it back to pro service.
After all YOU HAVE ONE LIFE and this is electrical device.
This is one of the reason why i finally ended with MCintosh.
Not all savings are savings in time function.

Thanks for all your replies.
The fuses look OK.
I'm thinking of selling it as it is, or getting it fixed.
This amp is so heavy, and shipping is a nightmare.

In the meanwhile, I have a spare AR amp and a Nakamichi Stasis amp, and will listen to them, and just enjoy music, no more playing around with cables.

I would just try replacing the output transistors myself.

I think you’d be hard pressed to find anything new less than $5K or even more to replace the SA-102. Selling it as is would be a big loss (to you) or perhaps a great gain for someone else who can fix it and enjoy it. Your money your choice.
