Recapping a CTC-15 clone

[blue_lateral]

Over the past few days I have been going through the Silvertone chassis looking for drifted resistors and so on. This set has pretty high hours, so I expected it to be pretty cooked. As it turns out, it's not that bad. Ive only found about 5 resistors so far that are out of spec, and 2 of those were stuffed with the wrong value in the first place (apparently). Now I guess I need to do something about caps.

Most of the small caps in this set are orange drops, dark purple things that look like orange drops, and ceramic disks. I was planning on leaving all of that alone, unless there is some specific problem. What do you guys think?

There are a few caps in here however, that I dont know what they are. I think they might be paper. There are about 5 of these tubular ones, that look like paper caps, but the "paper" tubes feel like they are ceramic! Are these any good?
