[R-390] Rebuilding C551 - BTDT?

[Renée Deeter_k6fsb]

I've done quite a few-

To rebuild C551 first remove it. Next drill a small hole (#60 or 
smaller) in the bottom to allow the vapor to escape while unsoldering 
the bottom. (Please think SAFETY FIRST). A small torch was used to melt 
the solder in removal of the bottom and cleaning it up. Do this upside 
down (terminals up) to keep the PCB oil in the can. There is not much 
oil about a teaspoon, just enough to make a big mess! Remove and dispose 
of the innards properly. Then solder the new capacitor ie.
mylar 1.5 uf or 2.2 uf ,your choice of value(s), to the terminals, 
assemble and tack solder the bottom back on. reinstall......
easy....
