The old “F’ fitting was just press fitted into place…not to mechanically stable against a hard cable YANK.
At least the disc ceramic input capacitor is still intact with adequate wire length. If you are proficient at soldering you can get this F-61 connector:

and unsolder the 4 \2 tabs mounting the isolation block to the chassis and straighten out the deformed hole and install that fitting without its control nut…[unless there is some remote chance that there is enough room to install that retainer nut internally if the cap leaves enough room inside ] and then the caps wire is soldered to the connectors center pin terminal. If it requires soldering the ground shell into the exposed hole, you pre-tin both pieces joining surfaces separately and then do a reflow soldering, it requires a heavy iron or soldering station due to the heat being carried off. Also, done as a quick operation to keep from melting the plastic pellet inside that is retaining the center pin connector. An immediate blast of freeze spray or inverted “canned air” on completion (the solder joints non-plastic state), suffices.
You’re certainly lucky that this intermediate isolation block averted your yanking a “F ‘ fitting out of the tuner proper …sitting back at the end of the RCA plugs link….the way most other sets are built.
