Yamaha CP30 noise

2016-05-10 by painintheamp@...

While this isnt a synthe, per se, it does have many of the same circuits as analog sythe stuff. That brainstorm said: There's waterfall noise in the audio on this unit. It's down to the stereo audio amp PCB. I replaced that four transistors in the two circuits to no avail.

Any ideas to make Mr Big Noise go away?


Thanks ,
