[NJARC] Capacitor question

[TrainBee at aol.com]

        I have a Philco 52-944, AM-FM tabletop radio.  The radio is in 
excellent condition and will be a great addition to my collection.  The problem is 
that there is a mica capacitor that is split in half at the seam (it is one of 
the rectangular types with the value printed).  It is a .047 at 400V. 
       Now that you have that, can I use a tubular cap to replace it, or 
should I use one of the newer silver mica caps?  The radio plays, but the caps 
that are in there look like they melted down a while ago, so I plan to play it 
safe and replace them.  
       

Any advise would help.
Thanks,
Joe Devonshire
