220uf, 1000uf, 470 uf caps are the main caps leaking. they are the black ones that are on the right hand side of the receiver when looking from the front. they are on the top side. the uf value isn't imcumbant of size. they have different voltages. IIRC, the 470uf cap is...63 volts i think. that's the only one i remember. at some parts, it's a light brown syrupy color, and at some points, it looks sorta coagulated and darker brown. the darker brown is at all times, farthest away from the cap. this may mean that it's just been around longer, or that it's actually the leak damaging something else farther away from the actual cap.
it has NEVER sounded bad to me. ever. i'd love to see it sound better indeed, if it has room to do so.
