I want to share what happened today because I know we have all been there.I am selling a 50s juke (although this applies to any coin op machine.) The damn thing has been working flawlessly for 6 months. The guy likes the machine so I put a song on. It picks up the record, slam dunks it onto the turntable and the needle skims across and spits the record off.I said to the prospective buyer this has never happened before and he gives me a sympathetic smile as you do to a child , looney or B.S artist.Why do these machine wait till you are selling them or having a party or showing off your latest restoration to do this. The coin op curse.
