The largest one listed in Philco's 1935 parts catalog is 12 uF, 450 WVDC.

I know Philco used some 475 WVDC electrolytics in the larger 1937-38 models.

(I have a 1937 Philco parts catalog somewhere but do not remember where right now.)

In Philco's 1941 catalog...they listed 8 uF, 500 volt wet electrolytics and up to 12 uF, 500 volt dry (probably paste).

Not knowing what Cornell Dubilier, Mallory, or Aerovox were making at the time...500 WVDC might have been the upper limit.
