So, here's where I'm at right now. After playing the set for a couple of hours, The intermittent video suddenly faded away into a blank white raster. I'm guessing something has gone open between the IF board and the Video amp tube, or the socket could be crap. They all seem loose. Turning the tuner has no effect on sound or video. Has anyone here had a similar problem with a predicta?
Also, as you can see, someone in the past cut a chunk out of the wooden base for reasons that are unclear to me now...
