The center dot looks painted, you can see wrinkles around the edges of the center dot which I don't think would be there if it wasn't painted, then again they usualy tried to use a contasting shade of brown. So it is orange brown orange, or 31,000 micro micro farads (picofarad in new lingo) for the first one, and 610,000 MMF for the second, both are supposedly rated for 500 volts if I read them correctly. They don't look physically large enough to be that because those values are huge for a mica capacitor? If you divide 610,000 MMF by 10,000 that comes up as a .61 microfarad capacitor, maybe it's supposed to be 64 mmf (pf) cap and the other a 33 mmf cap? Are those on the schematic?
