Here is another thing to look at- just below the coin comparator, you have a coin divertor which has a coil in it; coils are known to BUZZ when they wear out; an Irritating buzz. you can disconnect the Divertor wire and see it it goes away. You can also manually setr the coin divertor to the "Coin to hopper" position versus the "Coin to Drop Box" position; the divertor is just a piece of plastic that moves forward or backward. To manually set it, remove the coil hook up and just place a small shim in where it pivots forward or back; even a little piece of paper that jams it will work.- or you can try and repair to coil by wrapping it tight in back electrical tape or order a new divertor coil or assembly, (from Happ.com) both fairly cheap items. (If this is the problem)
