Yes now that you say it that is just what it looks like,But why only in those two area's?

I don't know what electrolytic cap's are! But if it helps the unit has two levels to it, and it is at the point of soldering them together that the brown
streak appears. j-n-t

I hope this pic is worth a thousand words!

looks like flux.


I wouldnt worry about it to much, unless you have idle problems.
