I have a koss KS4102 system also and mine does the same thing. its done it for almost 2 yrs now. ive taken it apart and noticed that the sound is coming from under the heat sink. im not an expert at home audio, but my best guess is its either the amplifier going out, or some kind of processor. but i do know from past experience that its probably going to be cheaper to buy a new receiver, rather than paying a pro to fix it, if it can be.

Car wont start suspect petrol pump

Turn your key to "ON" or "RUN" position. You should hear a whine coming from the rear of your car for a couple of seconds then stop.. That is the fuel pump priming your fuel delivery system. After you start your car, you should continue to hear the whine, but not as loud. That is your fuel pump delivering fuel to your engine. If you don't hear a whine then check all connections, fuses, relays related to your fuel delivery system.. If you hear the whine for prime, then check your fuel rail(s) for pressure. If you have pressure, then it is likely a Spark or an Air problem. Do you have any check engine warning lights on? If so, take to autozone (or similar) and they can check the error codes (DTCs - Diagnostic Trouble Codes) and print them out for you to work on.

Power steering pump is whining, I replaced it and the new one whines just as loud. what could be wrong

make sure your using power steering fluid recommended for the vehicle. If automatic transmission fluid it aerates causing bubbles. It's very similar to the effect of shaking a bottle of liquid detergent vigorously when half full. Having that much air in the system can cause it to whine very loudly and reduce the life of the pump.

97 Merc Grand Marquise just started a loud

If sound comes from under the dash, it might be an hvac actuator that is having a problem? Sometimes you can put your hand on it and feel the vibration? Sometimes with a relay, you can do the same thing.

D52w23 rca makes an awful loud high pitched whine

This is a coil, now a NOISY coil.. It is a common problem, and happens often. The whine is caused by current passing thru the copper windings and making them vibrate! A commonly accepted repair for this situation is to squirt some regular old super glue into the copper windings and let it harden for a few minutes..Viola! no more whine!

Continuous "whine" @ 1500 RPM only; and jerks/2001 Lincoln LS

Run the car from the top of a hill and let it coast at your whining speed. Put it in Neutral, does the whine disappear?
If not its in the drivetrain (wheels, driveshafts, tranny)
Very unlikely to be the timing belt. If it appears at a fixed speed then its drivetrain, if it whines at fixed revs its the engine.
Most likey the transmission I fear....Tires will also make loud whining noise too though...

My DAV-FC7 System squeals loudly.

If you can, use the digital optical connection....I had the same problem and switched to the digital optical connection and that worked for more whine.

It's grinding very hard when i put it in gear, drive or reverse.

Make sure you have enough fluid, and honestly, regardless of the fluid level, change it and put in new transmission fluid. If it's an automatic, change the transmission filter too. You can try adding some Lucas stabilizer as well. If that doesn't do it, you may be looking at a rebuild or replacement.
