 I'm on "re-stuffing" team. It's not very difficult to do , once you get the hang of cutting and gutting the pots. They solder back together easily.I just think it looks cool and is a very unique piee of electronics construction history-if you like that sort of thing.
Most are triple .05 uf/400v. I think the larger ones in the rear were .1uf/400v and .2uf/400v. Easy enough to figure out since the capacitance is written on the pot.The voltage input is 285V max , so 400 volt caps will be fine.

   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
