I thought I'd restore the power supply first. Then the main chassis.

The PS chassis is pretty green from the CAD plating.



I scrubbed it off using a mixture of 50/50 CLR and water. I used a green Scotchbrite pad I get at the Home Depot. I then used Q-tips to swab out the underneath part of the chassis. All was rinsed with Isopropyl alcohol and then dried.

When flipping it over one time, it slipped out of my hand and broke the E-Cap phenolic insulator. After removing the E-Cap (C2) I removed and replaced the insulator mount using some 4-40 screws, lock washers, and nuts. All better now. While I was removing the rivets on the mount I also removed the Candohm (R62) resistor. I then bolted on a 3.5K 25W chassis mount resistor. I'll never have to worry about that going bad! I also used some heat sink compound between the resistor and chassis.



I then noticed that in 2 places a grounding lug was riveted to the chassis. I cleaned both up with a small wire brush and applied some flux to the area. I used my 150W soldering iron to solder both of those ground lugs to the chassis. Only one is shown.
