Hi, I recently bought a fairly good condition Sharp GF-9191H off of eBay.
So far, the only functional deficit that I can find is that the treble and bass sliders are completely inoperative - moving either or both of them produces absolutely no change in the sound.
I've got the unit completely disassembled right now for cleaning and I'm looking for recommended solutions on restoring function to the sliders.
I've ordered some DeOxit, and will use that, but because it's only these two sliders (the others work fine), and because it's a total failure (e.g. it's not intermittent or static-y) I suspect it's not just the contacts.
Does anyone have any recommendations, before I reassemble the unit?
