They are Mylar/polyester film capacitors. Mylar is the trade name for DuPont's polyester film. They are likely being used as bypass capacitors (filters) but I'm not sure.

I've never worked on that version of that amp. Maybe someone who owns one would be willing to pull the cover to see what they are.

The value will read something like:
2A104J

*The 2A tells you that it's a 100V capacitor
*The 104 tells you that its a 10-0000pf (10 and 4 zeros -- 10,000) capacitor
*The J tells you that it's a 5% component

I was hoping with all the picture's i have and angles that i would have one that would show a size that i could compare to others on the board.The 2 are the only value of it's kind on the board and there are no others that are used on the board.It's not a huge deal but,would be nice to see with a test with and without them.
