Steve;
Now that is using your head! It is also inexpensive. I think we already have some straws. Scratch one item off the list!
Today I worked mainly on the chassis and managed to get the knobs cleaned. These are thumbwheel types and difficult to remove and reinstall. Fortunately I had good pictures before I took them apart. The confusing one was the bandswitch knob which has a captive lever assembly attached to it with a rivet. When reinstalling you have to get all the parts oriented correctly or they will not work right. Also the volume and control knobs are difficult to remove for cleaning. Each control shaft has a gear staked to the end of its shaft. The bracket that holds the whole assembly has to be removed first, then the controls have to be unfastened but not removed from the chassis. This provides enough slack in everything to allow removal of the knobs. Clean knobs using a fine wire brush - a tooth brush will not be adequate to get the grime out of the splined surface. When the knobs are replaced some juggling of controls and brackets is necessary to get everything lined up again for smooth operation.
One question I have is what color was the original background behind the dial glass. Was it a dark brown? This one looks as though it may have faded considerably. It also appears to be flocked and is also somewhat dirty. I don't know whether to chance cleaning it with something or leave it alone. The back of the dial glass has really delicate painted lettering on it. I don't think I will be touching that even though it is dirty (at least for now). I wonder if anyone makes replacement dial glass complete with lettering? Or perhaps a decal?
