Quartz Controlled Direct-Drive Fully Automatic Turntable System with Linear tracking tonearm (1981-83)
Turntable speed on the Technics SL7 is chosen automatically according to opto-electronic detection of the record size while the speed select knob is in auto position.
There is, therefore, no need to manually choose turntable speed or record size.
When the upper cabinet is closed, the stabiliser contacts the upper record label area to keep the record firmly in place.
Around the circumference of the stabiliser is a stroboscope synchronised with the quartz oscillator reference frequency, so that you can easily confirm correct rotational speed.
Platter: 300mm aluminium die-cast
Speed accuracy: within +-0.002%
Wow and flutter: 0.025% WRMS
Tonearm type: Dynamic balance linear tracking gimbal suspension
Cartridge type: EPC-P202 moving magnet stereo
Dimensions: 315 x 88 x 315mm
The SL7 was better still, giving improved detail, and it was also found to sound better than the original SL10 - £220 HiFi Choice 1983

Better than the SL-10 due to the fact that it has the same specs and is less complex.
The SL-7 is a bit heaver and is much easier to repair. The controls are on the body not on the lid as the SL-10. The circuitry for the arm transport and the auto size selector simplified too.
There is one major difference in that the SL-10 has a built in phono preamp and minor ones such as a label lamp and a manual spin button to aid record cleaning.
The reason for the 9/10 is as mentioned before for many linear TT is the lack of cartridge selection due to the need for a T4P type.
In conclusion Save yourself some bucks and get a SL-7 Vs a SL-10.
