RCA vacuum tube top caps replacement 5/16" contact pin anode connector electrode 1920s - 1970s - Metal

These five top caps have been removed from broken tubes. Many of them have vintage glue inside them, and many have a well soldered wire still attached as well.

Since caps become loose and fall off fairly often, we wanted to make it possible for you to repair your damaged tubes. Simply clean the solder off these used caps, solder a little extension onto the tube's top wire, thread the new wire through the cap's hole, glue the cap down, and resolder the wire to the top cap. Fun, right? If the wire coming from the cap is still well connected, you might just solder it to your tube's wire and glue the whole thing down with Gorilla Glue.

These are all 5/16" in diameter.
