OK, so here's the dealio, the power switch is working its just very sticky (it engages like it should, but it disengages with a little force, which I think its because the pushbutton mechanism needs a good lubing with WD40 or something like that. 

However the preset buttons though I think are a lost cause because the little phenolic wafer in there that sets the travel/locks in the preset buttons is broken (see picture below), and unless there's a way to repair that I think the preset buttons are just going to have to remain unusable unfortunately.
