I repaired one of these several years ago. Exact same appearance. The PC board traces between two high voltage signal have too little clearance, and the fiberglass resin in the board charred.

It takes an hour of work and some carving skills.

I'll see if I still have the documentation on the repair.

Something burned out on the board - either the transistor or something beside it (see picture). I think I've read before on this group about this happening with this board.

Anyway - repairing it is beyond my competence (or comfort) level but I'd love to get this clock working again, so if anyone can repair this or recommend someone who could please let me know.
