Don, Many thanks for the response. I just wanted to double check on that. I guess what threw me was the previous step to remove the anodized coating.
"Locate the two machined standoffs on the pedestal, labeled S in Figure 29. Lay the sanding block across the top surfaces of both standoffs. Keeping the block parallel to the pedestal at all times, carefully sand off just enough of the black finish to expose the top surfaces of the standoffs. Do not remove any further material, since this may affect proper spacing of the power transistors." That combined with the absence of solder mask around the mounting holes in the board caused me to second guess what was required. I did not want the finals to start flying due to a missing ground. Thanks again. I will proceed as if I knew what I were doing :) -Pete > > From: "Don Wilhelm" <[EMAIL PROTECTED]> > Date: 2007/03/08 Thu PM 11:24:25 CST > To: <[EMAIL PROTECTED]>, > <[email protected]> > Subject: RE: [Elecraft] KPA100 mechanical assembly question > > Pete, > > The heat sink assembly is an extrusion, and may have some warp to it.
