I have a couple of questions concerning the regulators/ heat sinks for the bugle P/S. Which hole should I connect the regulators to on the sinks? If I connect them to the top hole, the legs of the reg. barely go into the holes on the board. If I use the washers under the sinks, the legs won't reach into the board. If I connect them to the middle hole, some of the body of the reg. sticks out under the notch in the sink. The heat sinks that I have, which have the correct number on the package from Digikey (HS 191) are 1.5 inches tall. They appear noticeably taller than the ones in the picture of the P/S on the front of the manual. Also, do I use some compound when I mount the reg's. to the sinks, and should I use insulators between the reg's. and the sinks?
