I cut C78 and C77 open using a tubing cutter after removal from the chassis. C77 was the original Philco wet type capacitor. C78 had a large nut and washer on its bottom and the plastic threaded stud broke off as I was unscrewing the nut. I will have to use some epoxy to glue it back together. The internal parts of C78 were embedded in a hard wax or tar material. I had to use a hair drier to soften it enough to get the capacitor element out. I used a 3 inch long deck screw to pull it out.
C77 was completely dried out when I opened it up. I did find that a 1 inch PVC tube fit snugly inside this electrolytic's can, so that will be used to provide strength when the capacitor shell is put back together with a new axial lead electrolytic inside. The + and - leads will be brought out through the hole left in the bottom part of the old capacitor shell when it is remounted in the chassis.
I cleaned off the chassis where the two electrolytics and the control bracket had been. New rubber grommets will be needed for the control assembly mounting to the chassis when it goes back together.
