+1, I have a couple of 465s. The power supply is probably the same. All of the ones that I have repaired, including the one that I have on my bench have had bad power capacitors.
This old capacitors are big cans with several tabs for ground, the problem is that new caps are much smaller that the old ones and putting them back on the board is awkward as you need to make sure that you ground all the holes around each cap.
In a forum, don't remember if this one or other, a member had made round circuit boards to mount the caps so it becomes really easy to mount them keeping all the holes grounded. Here is a picture of what I did. I still have some of the disks, I will order more in the future, I know that I have the gerbers somewhere if you want to order them.
