   You  can  rebuild the cans yourself.  This is how I did it. I carefull
   removed  the can by uncrimping the bottom. Once the can is loose, clip
   the  old wires holding the can to the socket. Boil the can in water to
   soften the tar. Dig the can clean. Once this is done, clean the socket
   and  drive  the old pins out from the bottom. The best way toi do this
   is  to  drill a hole in a board. Place the socket on the board so that
   the  pin  will go into the hole as it is driven out. Once the pins are
   out,  replace  them  with #10 solid copper wire. Oversize them on both
   ends  for the time being. Once they in place, epoxy them into place on
   the  top  (Inside  of can). The ground pin should be long but not long
   enough  that it will short when the can is reassembled. The other pins
   should  be  cut  off  short but long enough that they can be soldered.
   Install  the new caps. The completed caps should look like a christmas
   tree,  with  the  long  wire being the support column. Once completed,
   replace  the  can  and  carefully  recrimp.   Cut  the pins to fit the
   socket.

   Good luck, It isn't as hard as it looks Richard May W8FCW
