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

From the cathode of the 7Y4 you will have around 215 volts. The 20 MFD capacitor from the 7C5 is cathode bypass. This one can be 25 to 50 volts. Be sure to replace the buffer capacitor with a 1600 volt rated capacitor.
