hey foxyyy,
i also once owned a nad 505, but too bad, out of commission na. the cd transport conked out on me, typical problem with mechanical / moving parts. so if you want to further the life of that wonderful player, don't use shuffle / random mode that often when playing cds. (para di malaspag kaagad yung transport).
i also wondered if it was an original nad cd player. i also surfed the net for info, pero wala akong makita. look at the back of your player if it has a serial number.
please pm me on where you bought the player (address, tel no., etc.)... bili ulit ako, yung single disc na nga lang.
thanks bro
