UPDATE: Feb.17.2010 - Please note that the A14F recitifier diodes are installed backwards in the above and below images.
Tonite I installed the LM323K voltage regulator (5v / 3a).
A pair of magnetized wire strippers came in handy to drop the screws into place. Needle nose plyers would have worked fine too I guess. I used a tiny amount of masking tape to tape the washers to the screws so that I could drop them into place easily. The area is too tight to get your fingers into (maybe you can, but I could not).
This was a bit more frustrating than I thought it would be, but everything is now soldered into place. There are 2 insulating washers in the upper left of the image above. You do not need these insulating washers - Just bolt the LM323K as is, to ensure a good grounding connection to the PCB.
