Pioneer QX-4000 Super clean quad w/speaker plugs [Expired]


no longer for sale

This is a super clean quad. I have all 4 speaker adaptor plugs. I recently used De-Oxit to clean the pots, cleaned what minimal dust was in the cabinet, checked all lamps and functions. There are no issues with this very nice vintage quad. This face does not have any scratches, gouges, nicks, etc. The wooden cover is in good shape but has a few minor flaws on the back edge. It functions perfectly as it sits now.
