I just aquired a NOS Laserdisc player from 1983. The player was brand new in the box with all its original packing. Suprise.. suprise, it didn't work. So much for the coveted "NOS" The slider jumped a tooth so re-setting that wasn't too much trouble. When I got the unit to play, It did not track nearly as well as a used unit of the same model I have with 8,000+ hours on it. For some reason people got into there heads that NOS means the unit will be absolutly perfect....This is not true.
Asuming the slave labor working in the sweatshops over-seas assembled it correctly, what could be wrong? Ignorant collectors will spend big $$$ on a new old stock unit but will pay considerably less for a comparable used unit that really is in good working condition,. Go figure.
