This is a circuit I would like to try to build. I have one problem with this thing, I can't tell what capacitor types Jim wants me to use based on his instructions. He says: 1) Do not use ceramic capacitors anywhere. 2) Use Mylar or Silver Mica. 3) 0.01uF=Polystyrene Preferred. These instructions just don't make sense to me because a bunch of the values are way too big for Mylar/Silver Mica and a bunch of the capacitors on the schematic are polarized, this seems to me he is indicating electrolytic, right after saying not to use them. I guess you have to. Here are the capacitors on the schematic, what kind do you think they should be?
10000pF - Use polystyrene like Jim said? Are there more modern choices that would work? Could polypropylene be used instead? How about mica?
5pF - mica?
6800pF - mica?
.1uF - since ceramic is out, I guess we must use aluminum electrolytic?
.47uF - since ceramic is out, I guess we must use aluminum electrolytic?
1uF - since ceramic is out, I guess we must use aluminum electrolytic?
15uF - Aluminum electrolytic?
10uF - Aluminum electrolytic?
47uF - Aluminum electrolytic?
100uF - Aluminum electrolytic?
