:mad: I was watching MI 3 this evening and when the bridge scene was on I heard a buzz then smoke and my center channel amp got fried,
Boy was I pissed and I checked the fuse which was burned and I opened the amp up and the heat sink smelled burnt and the caps right next to it ,
so my question is what could have fried and how much do you guys think it will cost?:eek:
It is an audiosource amp 100 bridged to 160 watts which really never even got warm for the past 2 years I have owned it and now poof.:(

Perhaps it's because it was bridged. Most amps when bridged can not drive low impedence's (below 8 ohms). My guess is it finally gave up the ghost in a big way. Another possibility is just plain old component failure. But if I had to guess running the center in bridged mode might have been to much for the amp long term.
H9"Appreciation of audio is a completely subjective human experience. Measurements can provide a measure of insight, but are no substitute for human judgment. Why are we looking to reduce a subjective experience to objective criteria anyway? The subtleties of music and audio reproduction are for those who appreciate it.

Well I guess I am one of the lucky ones to have a friend who repairs my stuff for me and is only charging me $50.00 to fix it.:DMy gear,

Is it possible that the speaker cables were touching? (i.e. even a few of the positive strands were wandering over to visit with the negative terminal (or vice versa) That would create a 0 ohm load (or there abouts) and could easily fry a bridged amp.
Other than that - just unlucky timing. (didn't spill anything into it did you??)

(anyway - sorry to hear about the amp, but glad to hear about the relatively inexpensive fix)Mains.............Polk LSi15 (Cherry)
Center............Polk LSiC (Crossover upgraded)
Surrounds.......Polk LSi7 (Gloss Black - wood sides removed and crossovers upgraded)
Subwoofers.....SVS 25-31 CS+ and PC+ (both 20hz tune)
Pre\Pro...........NAD T163 (Modded with LM4562 opamps)
Amplifier.........Cinepro 3k6 (6-channel, 500wpc@4ohms) -
I use heavy duty banana plugs and none of the strands were touching ,and as for spilling anything on the amp it was sitting on top of an A/V rack and I have no kids in my home.My gear,

Sorry to hear what happened to your amp Lou.
I would also guess that it happened because it was bridged. From what I hear it is not a very nice thing to do to an amp even though they say it can be done.
I would take the opportunity to simply get a more powerful amp and wire it straight.Marantz AV-7705 PrePro, Classé 5 channel 200wpc Amp, Oppo 103 BluRay, Rotel RCD-1072 CDP, Sony XBR-49X800E TV, Polk S60 Main Speakers, Polk ES30 Center Channel, Polk S15 Surround Speakers SVS SB12-NSD x2 -
Amp repair update,
my buddy rplaced the outputs and the caps and after a while of testing it blew out again. (good thing there was no charge)
I think I'm just going to just save my pennies and buy a used amp or try to find one on the bay since I still have $105.00 left over in my paypal account from a gift certificate.My gear,

If the speaker is OK, then it probably isn't the output transistors, but it is still a good place to work back from. I'd check em anyway if you smelled something on the heatsink.-Ignorance is strength -
