So, I've been trying to modify an AM/FM radio and am having some issue with one of the potentiometers (or at least I've assumed it as such).
It's 4-pin by the looks of things and whoever I wire it up I cannot get any response from it. I've only really used 3-pin ones in the past and I always assumed the 4th pin would either be either NC or a a duplicat eof one of the others.
Please see attached pictures. The 'Tune' dial is attached to it (using some cord to turn it from the offseted dial.
Any help on how I can go about wiring this guy up would be greatly be appreciated (assuming all traces to the board have been cut; I only want analogue values from it).
