As far as that cap on the crt, without a schematic in front of me, my guess would be that they're either trying to use it as a HV filter or they've bypassed a bad cap on the board. The schematic would show if it's suppose to be there. I'd take a look at my Siesta, but it's buried. I have a 21 out and in pieces, so I'll take a look. Bob Anderson has some very good videos about restoring these on YouTube. There's also couplates available online. About 50 if I recall, probably be money well invested. They affect sync.
