Anyone have any insight on this? -Ben K1NT
I am slowly progressing on my KPA100. I am at the part where the board and heat sink are temporarily mounted together to provide the proper spacing for soldering the final transistors. The five standoffs that go between the board and the heat sink are all 3/16", however, the heat sink has a machined depression around the hole for the standoff that is directly behind the center of the rear panel when assembled. Unless I missed it, the manual states I should not use a washer or lock washer on any of the standoffs between the heat sink and the board either on this initial assembly, or on the final assembly. This being the case, there is a gap between the board and this particular standoff. When I add the additional standoffs for mounting the shield later on, this will either prevent me from snugging the standoff down on this particular stud, or force me to warp the board at this point in order to get it snug. Surely this cannot be the case. While I haven't measured it, the depth of the machined depression in the heat sink would lead me to believe that a washer or lock washer is intended to be used either between the heat sink and the standoff, or between the standoff and the board during final assembly. Anyone have any insight on this? -Ben K1NT _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
