Semi-Automatic Direct Drive Automatic Turntable - mkI Servo control (1977-78) - mkII Quartz locked (1979-81)
The SL-1700 offers the famous Technics direct drive system with the added convenience of semi-automatic operation.
Once the tonearm is manually positioned over the lead in grooves, the automatic mechanism will lower the tonearm onto the record when the lever is flicked, and automatically return it to the arm rest at the completion of play. The unit is then automatically shut off.
This handy feature frees the user from rushing to the turntable at the end of record play and also saves wear on your stylus.
At any time during play, flicking the stop lever will cause the tonearm to automatically lift up and return to the arm rest.

After months of turntable scouring and research I settled on the 1700 MK I. Wonderful build quality, classy looks, and beautiful sound coming from this turntable. Feels like it might out live me. Coming from a Numark TT USB the sonics are noticeably more rich and fuller in range. Wow, couldn't be happier. The auto return feature is splendid as well.

The tonearm definately IS adjustable in height. (RTFM) Their is a screw on the right side in the lift assy. Push down the lift as the screw is a hex that needs to be un-locked prior to adjustment. Then adjust height of arm with screwdriver: clockwise is lower, anti-clock is higher.

I had one of these in the late 1970's. I'm very pleased to see that it made the top 10. It's a great performer for not a lot of money and extremely good looking. A winner all around.

I acquired a 1210 mk2 around a year ago and was really impressed, (see my review on that also). I then found this on ebay, and after some work on this 30 odd year old I finally have it fully working.
This is another step up again due to the suspension system on it, as I now have even less background noise. Not only no rumble, but no feedback or footfall noise of any sort even when on high volumes. Coupled with my usual Ortofon VMS 20E II cartridge, (Now with new stylus) this turntable gives excellent stability, and clarity, with all instruments recognisable, regardless of genre. The 1210 also managed this, but this is even better. Definitely staying with these two now, and have actually sold my old Dual and Ariston decks.

The only big difference on this model compared to top of the line is the lack of Qurtz control and a tonearm that is adjustable in height. The 1700/1710 is due to my opinion the player that places itself in the category Value for money
Quality in each piece and a very reliable mechanical controlled automatic system. I bought mine 1978 and it has being used almost every day since that- now I've upgraded to SL1410MK2 and will separate from this one as I managed to refurbish the 1410 Mk2 (Note that almost all MK2 models needs a very difficult repair work of the armlift )
