[R-390] C-103 cap replacement

[Fred Stillwell]

 Good afternoon all,
   What is a suitable replacement for:    C103, 10 mfd. 300vdc oil filled cap. B+ line, in the R-390/URR ?This is the big round grey  cap mounted on the chassis near the front.
 In the  R-390-A,  C103, 50 mfd. @ 50vdc oil filled bath tub style, on the cathode bias line ?
I have several R-390/URR  with the original oil filled caps and  2 R-390-A thathave damaged C-103 caps.  I'm thinking electrolytic in both cases.  Any ideas ?
Thanks and 73's
