Hey all;

I've got an old tube amp with a lot of hum so I am going to replace the
filter caps. The problem is, they are in a can. The can says
10uF 350 (with a little trangle beside it)
10uF 350 (with a little square beside it)
2uF 350

I think I can figure that part out. The can has 3 terminals and is grounded
to the chassis. Can I assume from this that each of the terminals is the +
of the cap and the - is connected to ground? Also, how do I figure out which
terminal goes to which cap? What do the triangle and square mean?

On the bottom, you'll see corresponding triangles, squares, etc., to identify
the positive terminals. The negatives are the can unless otherwise indicated.
