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.
I need a close up picture of the board area between the remote power input and the speaker outputs. Mine has a few broken chips and I need to know their part numbers so I can replace them
PERFECT! thank you so much. Now I can go to the electronics store and buy what I need to replace them.
I'm not sure on the names. I need the round silver parts, and then the rectangular gray pieces number 223J100
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?

I had the amp uncovered in my truck and my sisters friend stepped on it. so its missing two silver capacitors and two gray ones. that's all that is wrong with it
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:

Ok thanks. There is one of the electrolytic capacitors on there that I can't make out the markings. It is in the second picture, the one at the very bottom in the center.
Thank you so much you have been a great help. So if I am reading them correctly the ones with markings 100 25a 1p0 are 100uf 25v and size a
That's what they appear to be except the A is the series, not the size. Measure the distance between pads and match them to the ones you choose as replacements.
