I found two problems with the tuning mechanism. The first problem was the two set screws on the gear that drives the dial assembly were not effective even after securely tightening them. This prevented the turning of the dial assembly. I replaced them with new set screws. The second was the plastic mask disc was stuck in the dial assembly housing instead of being free to allow rotation of the dial. Repairing this required complete disassembly, cleaning, and lubrication of the dial mechanism. The Philco Service Bulletin 273, Philco Automatic Tuning, was a good reference for the disassembly process.
