I just picked up a 2250 as well, already pulled off the caps and received replacement sil-pads from nico boom.
You definitely have some leaking caps there, pop off the plexi/non-connection side end plate and wiggle the caps off the direction of the long way of the amp (from end plate to end plate direction), then pull them straight up carefully. Clean the board up with some 99% IPA and q-tips. From your pics it looks like the transistors have more thermal paste used throughout than mine, but I do see some sil-pads used as well. You'll need to obtain these or paste if you plan to replace the caps yourself.
As for the plexi screws, you can probably find those at a hardware store. I haven't had much luck finding the gold plated set screws or shroud hardware at any hardware store so like holmis said, you may get some form valeks1.
If you have a chance to take a "micro" clear pic of the Fan Control Board, I could use one as my 2250 did not come with the FCB and I would like to attempt to solder one together if I can find the parts and layout.

i know i have the schematic for the fan board (daughter board)- i believe it might even be posted in the schematics thread.
I also know i have the gold screws you need and the two plexi screws you would need. I would have to dig thru some boxes but i know i have some of both of those.
ill check for the daughter board schematics.
