Here is the damage, apparent bad components and recapping of the A3 Inverter board for my 2465B CT scope.
On the A2A1 Regulator board, C1016 RIFA capacitor has exploded. That has grunged up some of the nearby components, but does not appear to have done further damage. The C1018 RIFA capacitor has cracked open, but not exploded. Almost certainly non-functional. Resistors R1016 and R1018 have both been severely burned. They may or may not be functional. There are a couple of other resistors with dings and scratches which I will replace.
Additionally, on the A3 Inverter board there are three more RIFA capacitors and it can be seen that all three are cracked. They may still be working, but probably not for long. The A3 Inverter recap does not include those because I need to order replacements. It can also be seen looking at the bottom on the replaced capacitors that one looks like it was starting to leak, a second appears to have damage to the bottom (pre-leak?) and I am not at all sure if some of the rest are slightly bulging or not. They certainly aren't completely flat, but that may be a construction difference.
The only gotcha during replacement is the large axial capacitors. The leads are too short. I had to snip some lead from the original capacitors to extend the lead length. Also, even though these replacements have increased voltage ratings, increased capacitance or increased thermal rating and much better ESR, the replacements are generally smaller. In particular, the radial capacitor which was originally mounted on its side because it was too tall can now fit upright with no clearance issues.
