On these old sams .0047 would mean .0047 mfd, but 470 would mean 470 pf (or mmfd as they list them) which is equal to .00047 mfd. Not always, but the ceramics are usually listed in pf, while the paper caps are in mfd, on electrolytics it usually labels the capacitance on the schematic with 'mfd' following the number. In order to find out the voltage of each capacitor and wattage of each resistor you have to look up the part number in the parts list.
