Electrolytic capacitors have a useful life span and ones that are in a 60+ year old radio are way past that life span so they need to be replaced. The problem is that manufacturers don't make them in the old twist-lock package so my solution is to repackage new modern capacitors in the same can.
Electrolytic filter capacitor ready for removal
Filter capacitor removed
Crimped edge ground down
Peeling the crimp away
Removal of the twist-lok mounting ring
Removal of the terminal board
Removal of the sealing board and the guts
Can, sealing board, terminal board, terminals, and mounting ring cleaned up
Verifying component fit
All can ready for assembly
Connecting together the four filter capacitors
Add sealing plate
Add terminal board
Sealing board, terminal board, and mounting ring installed and epoxied
Leads wraped and soldered
All units complete with label
Hey, really good instructions with pictures! Got to your page via a link in Antique Radio Forums. Going to do my first re-cap, an RCA A-23 second production unit. Seems to have the same style electrolytic capacitor, 20 mfd, 10 mfd, 10 mfd. Going to try doing it your way, you make it look easy!
