I successfully repaired the dial mechanism on my 90 cathedral. The hole in the bracket was worn, causing the spring behind the pinch disc to tilt the shaft up slightly. This caused the mechanism to slip. From the junkpile, I found a piece of quarter-inch ID brass tubing, part of the dial on one of those 1940s single-knob Zenith sets. I reamed the hole in the bracket big enough to fit the tubing's OD and soldered it in place, then cut it short enough so it wouldn't interfere with the knob. A drop of oil in the bearing, and it was as good as new.

If you have to do this repair, the rivets in the bracket will have to be carefully drilled out.
