Technics have been putting serial numbers on their SL1200 and SL1210 turntables right from release in 1972. This serial number 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 deck or the back. From 2008 onwards an actual full date is stamped on the tonearm base cover.
