Well, tonight I tackled the most obvious, I replaced the dial glass. To do this I had to remove the entire front plate. This sounds worse than it actually was. Of course there were all the knobs to remove. These are SERIOUS knobs, the kind with TWO set screws each ! Then there are eight screws with nuts and lock washers on their back, two of which have nuts and lock washers which are virtually impossible to reach, and one screw which goes into a standoff, easy peasey. One does not have to unfasten any of the switches or jacks on the front panel. There is enough loose wire going to them so this is not needed. The lens bezel is held in by four screws, two of which also hold guides for the tuning dial. These needed a little P B Blaster to loosen, but then came off readily. Replacing the dial glass itself was pretty straightforward. I did have to drill four holes in the plastic dial glass to go over little studs in the back of the bezel, and sand the edges of the plastic dial glass a little to fit everything. I also found a few remnants of the old dial glass inside the bezel, a couple of little pieces caught behind the studs, and a larger piece held in place by the dial pointer, which is held to the bezel back by a screw and lock washer. I removed the dial pointer, and sanded and re-painted it white. The piece of old plastic dial glass was very yellow and warped up. It is obvious that it would have needed to be replaced had it still existed. When the pointer had dried, I put the custom fitted dial glass back into the bezel, and clamped it in place using the pointer in the original manner. After that re-assembly of the front went pretty easily, except I left out the two screws and nuts and lock washers which are such a bear. I will have to make a custom tool to put them back. So, here's what the dial looks like now. I have my desk magnifier light shining through from the back to let you see what it will look like illuminated.
