67 Zenith Tube socket issue

[drh4683]

I had to fix a 6LB6 socket because of poor contact. On the zeniths like yours, there is a wafer disk under the socket that holds the pins captive and is secured to the tube socket base with a single rivit in the center. You can drill out that little rivit, and have clear access to the socket pins for bending them out. Simply replace the wafer disk with a small screw and nut and it'll be good as new.
