On the KPA-100, two different length 3/16" hex spacers are screwed down onto the long Allen set screws that hold the circuit board in place...When these spacers are tightened down, they make the Allen set screws very rigid...Four out of the seven spacers are visible after the board is installed...If you have a 3/16" open end ignition wrench, you can loosen these 4 spacers a bit by reaching in under the board with the wrench...This allows more flexibility to the long Allen screws and the circuit board can be slipped on or off much easier...Be sure to re-tighten them after the board is installed...Lacking an ignition wrench they could be loosened with long-nosed pliers, but I would not recommend it as it will surely mar the spacers...
>> I am trying to fit the PC to the heat sink but there is not a neat match of set screws to holes in the PC. No problems in screwing the set screws into the heat sinks (i.e. certainly not cross-threaded) but there is a tiny mismatch. I am very very reluctant to use any force (and I have to get it back off anyway).
Anyone else have this problem and any suggestions? Maybe a comment will make a change from K3 frenzy (and yes it does look great!)
