[R-390] R-390 C101 and C103 Caps

[Perry W. Remaklus]

I am working on a R-390 and C101 (10uf 600VDC B+ filter) and C103 (10uf
300VDC audio decoupler) are both are leaky --- both are paper in metal cans.

 

 It would appear to me that I can replace the B+ cap with a electrolytic
provided I maintain polarity. I can locate a poly cap for the audio
decoupler but it is expensive (Cornell Dubilier UNL series Electrofilm
Metallized polypropylene). Would a much cheaper electrolytic work here? 

 

Suggestions welcomed
