When I opened up the box this thing was FILTHY. I plugged it in to see if everything worked and the left channel was dead. Checked everything else and working 100%...even cassette. I opened it up and found the chassis had never been removed before, which was a good sign, so I took it out and cleaned all the sliders and selector switch with deoxit. Removed the speakers and man were they dusty!! Cleaned off the dust to discover they are perfect! The outer folds are a shiny dark blue and the cones and chrome center look fresh off the shelf. After a good cleaning I put it back together and both channels now work perfectly and it sounds great. That gold is really beautiful on these. I basically stole this considering how it functions now. The owner must have thought the left channel was blown cause it went cheap. Now I have a 100% operational M71...here are some pics...
