No, polarized for sure as they're Kemet hermetically sealed tantalums... which is why they still work after all these years.
FWIW, HP always noted the + terminals or pin 1 with a square pad on the their pc traces.
Yep, you're right, I see Kemet written on one of them. That's the info I was looking for. thanks. I have 2 cases where I see a problem with a cap but you're right, these caps are rarely the problem.
Funny thing, I went to Digikey today and ordered a set of replacement caps - before I read this, and ended up ordering Kemet axial Tantalums.
On the pads, the square pad for positive is true for the 65 and 67, but not for the 35, 45 or 55. These have a small triangle next to the positive pad.
