Since you have it working now, there is another option.
That the pot you got in there now - works and you will find yourself at a point where you no longer need to "play" with it and just use it. In that case just measure the resistance across those terminals that solder to the board - then remove the variable and use a FIXED resistor - solder it in the place of the variable and be done with it.
You can then use that variable back in the other radio you took it from to try and make this radio work.
- (...If you decide that the 2000 is going to be up for sale - then perhaps a variable is needed so the next owner can play with that radio as needed for their own entertainment and enlightenment...)
You can then keep both radios working or serviceable to a degree.
