Interesting! It looks like the legs of the pot make contact by pressure instead of being soldered in  :o

Push pot into position so tabs can be soldered in and the legs just make friction contact with SMD pads???

I cut the logs off when trying to remove the pot - it was just easier to get out that way.

Gotcha! Couldn't see the pic yesterday.

You need to measure resistance on all of the legs of the pot. The 4th leg could be a dummy leg OR it could be a center-tap. Depending on its usage, there are suitable replacements available.
