Hey guys, I ran across this post when looking for a fix for my KSP400's hum coming from the sub. I tried Trey's advice and replaced the filter caps. I did it on both amps, even though only one was humming. The large filter caps were broken and leaking fluid on both amps, so my guess was that the other amp would start to hum soon anyway. Unfortunately the large caps are sorta expensive. About $20/each and you need two per amp. So the total cost for the caps was about $90, and fortunately I had a friend who is good with circuit boards. They have been working well for about a month now and are extremely clean. If anything changes, I'll let ya know. Special thanks to Trey for getting me the wiring schematics!
