When I removed the KPA100 PC board to do the KPA100 Upgrade the thermal pads of Q1 and Q2 stuck to the transistors. I noticed that the bottom of these pads were silvery where they joined the heat sink. Some of the black part of the pads remained with the heat sink. I will replace these thermal pads. Should I attempt to clean off the heat sink surface where these pads left their residue? And yes, I will be very attentive in tightening these screws after a small amount of use in the future. These pads I am removing are not the original pads, so I don't think I have overly abused the finals. Thanks for any comments.
