Well that is an in depth answer. As for the unit,it is still running awesome.As far as I can tell the only problems are the lamps are out and the occasional crackled in the volume knob.it just looks kind of dirty.
I have no training in electronics repair but my buddy went to school for it,so if I do run into any trouble he can help out.
I'm thinking it should be more cosmetic work than anything thing.i just always like to talk to people who know more than me before I take on a task like this.
