I'm recapping a F-1740 that was mostly unmolested except that the 3 section filter cap was missing. The schematic shows a 20mf off the 7C5 output tube, and a 15 mf on the B+ and 10mf to the speaker coil. Unfortunately, the schematic doesn't give the voltages, only the mf values. (1940). I suspect the 15 and 10 are around 350 volts, don't know about the 20 mf. Can somebody give me a hand with what voltages correspond to which mf values? The original part no is 61-0089. Thanks
