HarrisonGrayLetchworth Posted July 13, 2012 Report Share Posted July 13, 2012 (edited) Well, I bought this amp from a guy off the forum. It has been a great amp, besides it will go into protect on fast pace bass music, like rock, from lack of battery power and my car HOGs up insane voltage. It can drop my D3100 to 13v with my radio off. And It runs a little warm. When it is hooked upto a DMM( like you are tuning it) while turning up the gain with a 40 hz test tone the amp will start buzzing inside once the output voltage hits 49ish. No clue what it is, i'd make a video but the camera would pick up my exhaust over the buzzing. More importantly I opened my amp today to see if it was dusty inside or anything and found some crazy looking wiring inside that looks like its been repaired, comments ? Or is this just how Exile builds their amps. Also the third cap over had a little bit of corrosion on the top of it, or thats what it seemed like. Does it look like the 3rd and 4th are poking out on top? Here is a full board picture.

diatribe Posted July 14, 2012 Report Share Posted July 14, 2012 A couple of caps look like their bulging on top. If they is, that is most likely the source of your high pitched sound. Get it fixed now before it breaks and save a lot of money. Look around locally for TV/electronics repair shops and see if they can replace them for you.

But not sure, hope i can get it fixed.

I'd find someone online who specializes in amp repair if I were you, that baby would be no problem to ship. Quote I'm gonna hate Link to comment Share on other sites More sharing options...
HarrisonGrayLetchworth Posted July 16, 2012 Author Report Share Posted July 16, 2012 Any suggestions or anyone to stay away from? We have a TV repair shop that has been around forever in town that I was going to see what they said.

8ight Posted July 16, 2012 Report Share Posted July 16, 2012 (edited) See: Capacitor whine. Give them the amp and tell them you need the main capacitor bank "the big ones" replaced with ones of the exact same specification. Advise them to cautiously remove the MOSFETs from the heatsink individually and carefully when disassembling the amp. EDIT: Anywhere you seek repair get an estimate, show them the amp, tell them what you want done.

Kranny Posted July 16, 2012 Report Share Posted July 16, 2012 some amps emit a high pitched buzz at the point where they start to clip. that amp doesnt look to be in the best shape, plus those torrid wires are real sloppy. i've never seen an amp have such snaky wiring like that.
