Most amplifiers have a protection circuit that should prevent damage when the speaker wires are shorted. My Vincent and McIntosh amps both shut off immediately when that happens...Don't ask me how I know....
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

Well, I feel so stupid about what I had done. Anyway, I was trying different preamps, different IC cables, different speaker cables, and different sources (CD/SACD players and phono cartridges). While I was playing around, I got a bit sloppy. I would still like to have the amp with a built in protection mechanism to prevent such case. It is so harmful to the power amp, but having no built in protection mechanism for $5K amp a decade ago does not sound right. I cannot find any clear damage from these two inside photos. Any of you see burnt components or circuits? Thanks much. https://photos.google.com/photo/AF1QipPSt_CM_-03crVgXYW6NBwEgfAXc3eNWuPSAlBJ https://photos.google.com/photo/AF1QipNIz2uuUz90t-qmUl15mIkIjsxDoqVbj8YsuPLa |
Plug your amp to a 'Dim Bulb Tester' to find out if any repair is required. https://www.youtube.com/watch?v=wRFRwOnLsZI&t=15s |
@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.
