What went bang, smelled of "I'm fried", yet left it in working order...???
Hi gang - wasn't sure if this should go here under amps or tech talk, but here goes: normally, I'd call the salesman I work with at my LAD, but they're closed Sun. & Mon. and I'm loosing sleep over this as I feel I'm on very thin ice.
My wife and I were watching a movie late last night, and after the movie we were sitting on the coach discussing it when we both jumped when we heard a loud bang coming from the media console and smelled an electrical burn. Sitting on top of the console is a Dan D'Agostino Progression Stereo power amp, a McIntosh C53 preamp, and mounted directly behind this on the wall, a Panasonic plasma TV.
Nothing tripped a fuse, the TV was still on, both sets of power meters on both the Dan & Mac were still lit. I streamed a test track that has a lot of bass that when I turn up to a certain volume, has the Dan's power meters hang at 400 watts for a few seconds, and they did - just like always. Everything seems to look and sound fine.
So, while I'm not asking for anyone to try and guess which of those three components made the bang, what I am asking is for any of you here who have an electronics background tell me what electronic part (in either the preamp, amp or TV) possibly could have made a loud bang releasing an electrical burn smell, yet "seemingly" leave everything still functioning as normal...?
--thanks and cheers!
@wlutke Thanks - that sounds like it’s at least on track with what I’m experiencing. Just wish there’s a way to tell if it was the preamp or power amp that did it, but I’m guessing it’s the power amp… |
@closenplay Thanks - I didn't smell anything around the plasma, but I'll check out the audio section on the plasma and see if it's still working, because yes, I never use it anymore. Boy, that sure would be nice if that's all it was. -cheers! |
@itsjustme thanks. I'm planning on calling my LAD salesman when he's back in the office to discuss. I looked inside the D'Agostino and no smell, no carbon, no swelling, etc. (just a little bit of dust that got through the top vents). The biggest problem is figuring out where it came from - based on the direction of the sound, it's either the D'Agostino or plasma TV. If the D'Agostino was light enough for me to pick up and throw in the back of my car, even without seeing anything or even sure if it was the culprit, I'd just do it and drop it off at my LAD... but, at 125 pounds, and an awkward carry because its front heavy, and having to go down a full flight of stairs, it will take some planning and arranging helpers. -cheers |
@imhififan -thanks. Yes, I had figured that was the MOV and it looks just as shiny and new as in the pic you posted... So, it's even more baffling now that you confirmed that is the MOV. -cheers |
