Was wondering if anyone out there had this amp and could take a picture of a certain part of the board for me. The amp I have may be missing parts near an op-amp and the layout numbers are unreadable on this board The op-amp in question is the one nearest the opto-couplers. I can upload a picture of the area for reference if needed.

Ups, nevermind... just checked on ampguts... I have an older version of this amp
They are both capacitors. The silver ones are electrolytic capacitors. The gray ones are film capacitors (probably polyester/mylar).
It's unusual for the film capacitors to fail. Have they burned beyond recognition or has someone removed them?
Do you know if anything else is wrong with the amp?

The 223J100 are 0.022uF@100v 5% tolerance.
The electrolytics appear to be Panasonic A series (probably discontinued). Use the FC series or equivalent if you buy from Digi-Key. Here is a datasheet to show the Panasonic marking codes:
