However: there are no designation, so I have no idea about the resistance (can always measure when desoldered), but the biggest problem is that in addition to the standard three legs, there are two legs connected to the pot housing. At first I thought it was just for making the pots sturdier (they are directly PCB-mounted), but there are several PCB traces leading back-and-forth to these extra legs.
So: any suggestions where I might find these kinds of pots, or any other solutions?
