Look for broken off caps. I have seen the tall green (polyester?)slim
ones break off very easy since they stand up higher than most other
components and Atari didn't seem to leave any spare lead space when they
soldered them to the boards, if they get bent over more than about 45
degrees they will snap off. I don't know reference numbers off hand but
they are very close to the DAC's.
Good Luck.
