Turned on my speakers recently and got a really high pitched whine out of the speakers. Something clearly went bad since they have been working for over a year in the same spot with no changes to wiring or anything like that. The whine happens without the speakers connected to the computer so it isn't the sound card or wires to the sub. I have read about people talking about ground loops but I don't think that is what it is. I can plug headphones into the control box and get good sound so I think the control box is good. I'm planning on taking the sub/amp apart later but just wanted to see if everyone agrees that is the problem. I have read through the forums and found list of parts. Best one I found is below. Replace --- Replaced with R527 (4.7 ohm) --- CPF34R7000JKE14 R529 (5110 ohm) --- CMF605K1100FHEK 680 ohm (PCB position not labelled) --- RN70E6800FB14 MR7 (100k ohm) --- CPF2100K00BEB14 D5 and D6 (FR204) --- FR204-B All three 22uF (50V) capacitors --- EEU-FC1J220 (63V caps because they don't have the 50V versions. Same size as 47uF caps, fits fine though.) All three 47uF (50V) capacitors --- EEU-FC1H470 Q10 (2N5551) --- 2N5551RLRAG (also has properly spaced pins, unlike the original. Pretty sure options are to try and fix this on my own. Pay 120+ to klipsch to try and fix, or elliot-tronics. Thanks for any help. Had these things working for 8+ years and really love them.
