I took apart the Sylvania set and gave it a bath in the driveway. Was pretty nasty looking. I then found it to have a toasted power transformer. I found an another chassis like it in the attic and brought it home for a donor. About the time I checked out and swapped the transformer, I caught a cold and spent most of last week and this weekend hocking stuff up!
Haven't got much further than that. I still need to change some caps out. I feel much better this evening, and hope to be out in the garage soon. Here's a shot of the cleaned chassis and the donor.
