Those Command Set receivers had a B+ dynamotor that supplied 250v at 60 mA. Many people operate the sets on lower B+.  If these little round "flower pot" caps are the ones you're looking at, they aren't soldered shut.  The edges are bent over the mica insulators.  Most people either trash the old cap pots or carefully remove, cut them open, restuff & either glue or solder the cut edge.

  I have a BC-453-B that has minimal hacks.
 At a recent hamfest I found a ARN-30 solid state dynamotor replacement.
 This power supply will properly mate with the receiver.
 Should this supply power the receiver properly?
 Some of the can capacitors along the side of the receiver are leaking.
 It looks like these have a soldered on top.
 Is it a lot of trouble to rebuild these capacitors?
 
 Thanks
