Liquid Arthur Posted April 8, 2018 Report Share Posted April 8, 2018 Hi, A friend gave me a Mmats amp. Old school cool all the way, I would love to run it, but... It powers on and will bump a sub, but it emits this high frequency noise from both the amp and the speaker. It's very loud. I opened it up and put my ear close and found where it is coming from. I have the arrow pointed to it in the pic. I think it's a funny shaped capacitor, maybe? I really don't know. Does anyone know, what it is and where I can get another one? Or is there a schematic I can get? Do you think it is likely the culprit? My other problem is, I don't know what amp this is. The model stickers have fallen off. It could be a D200 HC, but I'm not sure. I'm posting pics, to see if anyone knows exact what model. Thanks in advance. Link to comment Share on other sites More sharing options...
CstrokerV Posted April 8, 2018 Report Share Posted April 8, 2018 Does it do it with gaIn all the way down? Noise from amp can be gain set to high noise in speakers can be bad ground as to model I couldn’t say my build http://www.stevemeadedesigns.com/board/topic/142505-small-build-log-4-dc-lvl3-10s-tl-update-link-to-rebuild/ http://www.stevemeadedesigns.com/board/topic/154258-rebuild-6-lvl3-12s-update-small-video-nothing-spectacular/ new build http://www.stevemeadedesigns.com/board/topic/188181-03-trailblazer-slow-build-8-dc-lvl3-12-m1-motor-m2-parts/ Link to comment Share on other sites More sharing options...
CstrokerV Posted April 8, 2018 Report Share Posted April 8, 2018 Google 1999 1200 watt mmats amp you might get the model name mber my build http://www.stevemeadedesigns.com/board/topic/142505-small-build-log-4-dc-lvl3-10s-tl-update-link-to-rebuild/ http://www.stevemeadedesigns.com/board/topic/154258-rebuild-6-lvl3-12s-update-small-video-nothing-spectacular/ new build http://www.stevemeadedesigns.com/board/topic/188181-03-trailblazer-slow-build-8-dc-lvl3-12-m1-motor-m2-parts/ Link to comment Share on other sites More sharing options...
Liquid Arthur Posted April 9, 2018 Author Report Share Posted April 9, 2018 I've tried googling it amongst other searches, and believe it to be one of the D?00HC Series, trouble is all three of them look exactly the same once the sticker falls off. I'm hoping someone will know it by the "21410" sticker on the bottom. It makes the noise even hooked up on the bench, I'm not sure about the gain, I may have to play with that.

Broke_Audio_Addict Posted April 9, 2018 Report Share Posted April 9, 2018 @BigDWiz could probably help you identify it. That being said a lot of people's definition of "music" is a clipped 30 hz sine wave with some 80 IQ knuckle head grunting about committing crimes and his genitals.

Yah, I know, but it's $150 plus shipping and no warranty. A lot of $$ to replace possibly just one capacitor. Plus I don't learn anything that way.
