The following article has a section discussing the pros and cons of installing quick-disconnect connectors on the big PC board:

Scroll down to "Adding Quick Disconnects to the PC Board."

As explained in the article, I decided that the cons outweighed the pros. A thoroughly restored Predicta should not need frequent service that will require pulling that board out repeatedly.

Regarding the couplates, on any other TV I'd recommend leaving them alone and waiting to see how the recapped set behaves during a prolonged bench test. Having restored two Predictas, and recalling how much I disliked removing and reinstalling the big PC board, now I would lean toward replacing them preemptively. The article referenced above has sections on replacing couplates, but notice that it describes a different Predicta chassis than yours. The following article mentions couplate replacement in the pedestal/Holiday chassis:

As seen in the photo below, the couplate replacement can be simple -- a few parts wired onto a chip of perf board.
