Hi Kurt.
It's Best to replace all the Electrolytics and cardboard tubular caps. The Mica caps are generally okay. I've gotten most of my Capacitors from "Just Radio's" they are great to deal with and has a good selection. You can buy capacitor kit's from them as well. that will give you a good selection of the sizes most often used in pre-war radios. I use the metalized polypropylene caps with a 630V rating. you should always use a voltage rating either equal too or greater than the original, never smaller. Also when replacing the electrolytics remember to observe the correct polarity when installing. Installing an electrolytic cap backwards can turn it into a firecracker !!!!!!!! Regular caps can be installed either way.
