The stereo amp that I built (one of my earier threads)works perfectly,it plays the MP3 with good sound quality and volume response,however there's a very faint whine (you can only just hear it) when the engine RPM increases,I assume this is coming from the charging system,can anyone suggest a suitable choke or similar device,would a 2.2uF condensor(the type fitted to the back of a car radio)be any use?If I can't get rid of the whine I don't think it will do any harm? Thanks to all,Happy easter.
