Would you believe the original Philco service manual for the 48-1256 does not give the working voltages for these electrolytics?
So...using the part numbers given and looking them up in the Philco 1950 parts catalog, here is what I found.
C101, C102: 30-2575-11 - 15 uF, 200 WVDC
C103: 30-2575-12 - 40 & 10 uF, 200 & 200 WVDC
I would use caps rated at 250 VDC. You probably won't find 15 or 40 uF; use 22 for the 15 and 47 for the 40 and you'll be OK.
