@DL8WOW - Jens,
Actually, when I look at the photograph you have two options here:
1.) Just replace the matching transformer with a new one from either Mini-Circuits or Digikey
2.) There is hope for the remaining leads on the transformer - they’re just sheared off at where they connected onto the pads on the board. It may be possible to heat up the ends of the wires (they’re bent around, but they’re in the approximate location where they were sheared off), add a little solder, and then heat them up enough to solder to the pads. It won’t be ‘factory fresh’, but it’s at least going to give you back the Lowband port on Receiver 2.
By the way, NEVER think that your Lime is scrap because of something like this. You have MANY more ports to use on the Receiver 1 and Receiver 2 port sides (in your case the Wideband and Highband ports) and both will suffice for V/UIHF and with the mods HF. A simple fix to this Lowband Port on the Receiver 2 side and you will be back to health again…this isn’t terminal.
Heat up your soldering iron and be careful with it - it’s entirely salvageable even as it is and should work just as well as it used to be before the mishap.
