There are 2 "twistlok" (can) caps. whose diameters need to be measured. You will be increasing the amount of capacitance in the reservoir (C1B) and decoupling positions (C2A/C2B) using modern, clamp mounted, parts. Obviously, the clamp sizes appropriate to the chassis holes already present need to be acquired. I will "ping" Jim McShane to get his input on the subject.
Remember, C1A is being replaced by a film part that's cemented into place on the underside of the chassis.
BTW, I see only 1 diode in the bias supply. It was a nice touch on Pilot's part to full wave rectify the bias supply. Perhaps that area should be gone over too, since corners may have been cut.

Follow Ups:
The smaller twistlock can is 1" in diameter, the other is 1 3/8". Both are currently empty (I cut them apart and cleaned them so they could be stuffed with new caps as needed)
There is a second diode, hiding under the wire on the perfboard.
Stuffing and "gooping" is OK, but clamps are definitely more secure.
Let's see if Mr. McShane posts.
