ON pages 42 and 43 of the KPA 100 manual, it discusses Crf. I cannot remember ... but was that modification around when the installation of KAT2 and the KBT2 or is that something really new because of the KPA100. I have it all installed but cannot remember if the capacitor is there and I am not looking forward to taking off the bottom, heat sink of the K2...just to check. Anyone have a comment? Lee -K0WA
