I read there are a few guys you can send your radio to and they will refurbish it for you... Id hope that would be cheaper than flee bay but who knows... Problem was, when I looked at a couple of the companies the links were either dead or had little to no current info.
Factory radio 83-87. AC DELCO 2700 ETR
Im having issues with mine ('86)... It puts out good sound, but the front screen has a LED that doesnt always work, popping when adjusting the volume knob, and the signals to the speakers randomly goes in and out.
I'd like to fix it if not too expensive...
