Arran, I'm using plastic caps to get away from electrolytics that dry out eventually. Same for paper caps as I've had them disintegrate before I could get both leads unsoldered. So much for testing a component that's in 2 pieces. I use better capacitors and higher tolerance resistors than Philco used so hopefully my radios will be playing long after I'm gone. My concern was only for the working voltage on my Philco 20's filter caps, but I've just gotten some Solen 630v units to replace the black mess I melted out of the can. For the Japanese radio, a wire wound resistor screwed to the chassis will be the simplest solution to get 100v to the primary.
