I bought this old 70's style receiver from ebay recently, and after i hooked it up to e'rything else, and started to play something with it, it cut out during the middle of a track, and now it won't play anything. I only had the volume at a mormonesque and conservative level of four, so i don't think i killed it by turning it up or anything. O .o I smelled something burning before it cut out, it smelled like burnt black powder, but my dad said it was probably just the light inside heating the dust off of it or something. Now it's broken. What broke, and can i fix it?
