So, after some time sitting off to the side I got my KSP amps fixed. First, I took them to the repair guy here locally and he instantly said "I bet it is the filter caps", so he replaced them and it was all good for a couple days and then bam, it's back. I got to looking through the service manual. Low and behold under trouble shooting it said......."Excessive Hum-check all filter caps", so I changed all of the filter caps on the amp module (including the big 6800uf main caps, got them for just over $6.00 apiece shipped from NY) and the two other small caps that were not listed as "filter caps". The amps both have a very slight hum that you can hear if the house is extremely quiet, computer not running, fridge not running, etc. From my couch I can't hear the hum, but if I get down right next to the sub I can, that might be normal I don't know. Other than that, they are sounding very nice! I got all the caps for both amps for about $50.00. Changing the caps was a breeze and they sound all that much better because I DID IT! haha.
