[QUOTE="shorai, post: 1118305, member: 24498"] I would go pretty much with my first answer :- Causes - Manufacturing differrences (dry joints etc) - Manufacturing differences in components (one component made on Monday 13th) - Defects in components , one gor dropped - Design and layout differences left to right- one power lead routed slightly differently acts as a differentr antenna to pick up RF signals (yes!), detected by diode capacitor pair(transistor, mosfet, etc) acting as a crystal set Remedy If your problem can be isolated to a switch etc, put a Balun over it's leads (also the power and other leads to your amp). There is a very good reason for data cables to have bulges near rhe ends, they are Baluns to get rid of noise that the computer feeds through those cables acting as aerials. You can get good quality clip on Baluns from any radio repair shop. Try Mantech if you cant [URL]https://mantech.co.za/Stock.aspx?Query=clip+on+ferrite[/URL] [/QUOTE]
