To fix this it was a simple fix of replacing the 2K Ohm standard potentiometers for voltage adjustment with a 10 turn precision potentiometer.

Insert the new potentiometers in their places.

Solder all four wires back to each post.

Put new 10 turn knobs on the front.

Plug power supply in and test functioning.

Put cover back on with four #1 philips screws.

You are done.
