Technics have been putting serial numbers on their SL1200/SL1210 turntables right from its first release in 1972. This serial contains the year of manufacture and in some formats the month as well. It will be a 10 or 11 character serial number consisting of both numbers and letters and is located on a sticker on either the bottom of the unit or the back. From 2008 onwards an actual full date is stamped on the tonearm base cover.
