Technics was a major player in the turntable market for many many years. This Technics SL-1600 was one of their offerings from 1977-1978 (though I have seen earlier dates mentioned) and is a Servo Controlled Direct-Drive Automatic Turntable. It had a retail price of $290.00. In 1979 Technics came out with the SL-1600 MKII. The MK 2 was a quartz locked version and had the controls on the outside of the dustcover as opposed to inside like the standard SL-1600.
While the MK 2 version of the Technics SL-1600 is probably a little more popular among vinyl spinners due to its quart lock mechanism the SL-1600 MK1 is still in pretty high demand. They sell from around $200.00 for a functioning average unit up to over $300.00 for a fully functional and cosmetically nice table.
