[sdiy] Semi-OT: odd capacitor values

[rsdio at audiobanshee.com]

Does "MFD" stand for millifarad or microfarad? If the former, those would be 105 uF and 255 uF.

Are these really 0.105 microfarads and 0.255 microfarads capacitors, or does the last digit 5 mean something else? I have read that Hammond hand-selected the capacitors back then to match them with accompanying transformers/inductors. Why would they have chosen such odd values? Does anyone know?
