I have recently acquired a compact repwood radio, a R-22-S manufactured by RCA Victor in the early 1930s.

The schematic does not specify voltage values for the electrolytic caps. Based on the vintage, my primary guess would have been that they were in the 450V range--but they are actually rather small waxed cardboard box affairs that appear to be the originals. Note that they are also multi-part caps.

Unless they are especially advanced for the era, I'm now assuming that the voltage ratings are actually lower than I had assumed.

Would anybody out there happen to know the proper values, or have advice on the matter?

Any help is most sincerely appreciated!

Here is the schematic:

No power transformer in this set. 160 VDC filter capacitors are fine.
