Goo evening all, I am on page 37 of my KPA100 build, getting ready to solder the finals on the board. After fitting the circuit board to the heat sink, I noticed that the bodies of transistors Q3 and Q4 prevent the circuit board from resting on pedestal standoff shoulder beside Q3. The transistors are flush with the bottom of the circuit board, but Q3 and Q4 are ~.095 inch thick, and the shoulder is only .075 inch higher than the pedestal. I realize that the transistors need to be able to be snugged to the heat sink for thermal transfer, but that standoff should make contact with the ground plane of the board. The manual mentions several times not to use washers between the sink and the board, but shouldn't there be something there? I looked forward in the manual, but did not find find anything that addressed this. Is this a non issue? Thanks, Pete wd4lst
