I have a broken pot on an Ibanez pan dealy. It says 100kB. Although it has 5 little lugs coming out of it into the pcb.
Anyone know what should be happening here?

Are you sure there are not 6? Some dual gang pots have all 6 leads in one line.
Yeah I double checked. the lug that looks missing is the middle one of the second row if that makes sense
Just a guess, Is it possible that the pot also has a switch in it? Or is one of the lugs still attached to a wire that broke off? Just something else to think about.
Peace!

I've seen numerous miniature dual-ganged pots with a non-standard number of pins/lugs on computer speaker amps. Pretty common. Although the input and output of, say, a dual volume control are coming from and going to different places, they are both going to the same ground. In which case you only need 5 pins instead of 6. I have some 16 slider-pot assemblies made by Alps that I bought surplus 12-18 years ago (I think they may have been used on Alesis EQs). You'd think that 16 slider pots need 48 pins, right? Wrong. Not when they are used for voltage control and share a common contact for voltage source at the input, and ground on the other side. Eighteen contacts will do nicely, thank you.
Maybe it's just a regular pot with two outer "lugs" (totally disconected from circuit/pot) soldered just for stability.
I've seen this configuration in many tv/stereo/monitor that i scavenge for parts.
I think it's probably just a normal pot with 2 external lugs connected to the body of the pot. This is probably the case if the solder blotches for the 2 outer lugs are reasonably bigger, and the pot is board mounted. This sort of thing is pretty common in stereo systems...

The two outer lugs are defenitely there just for stability. they both have thier own seperate traces back to the main board. I'm think that Mark could be right with his idea that there is a common ground pin for the two gangs.
But I can't be sure as since the pot is dead I can't test it. :cry:
Oh well
for your interest the pcb holes for the pins go like this
o 0 o
o o o
(oh and there are two big earthed pins coming from the base for stability)
THanks!!!
