Technics SL-1700 feet

And if you want something very special just remove all feet and put your Technics right on the flat and fully udjustable rare Audio-Technica AT616 Pneumatic Insulators.

If they are standard like all technics feet then you can upgrade to ISONOE, i've been using them for 7 years on my upgraded SL1210mkII 

@john421 just add ISONOE and you will be fine, for higher budget buy AT616 Pneumatic Insulators (very rare) as they can support much higher weight up to 130lbs (can be used under any turntable, including superheavy ones if you will ever upgrade your SL1700)

The original Technics feet must be replaced on any old Technics turntable, no matter which model, those original feet provides ZERO isolation and Technics notorious for bass feedback picket up even by MM cartridge. So the first thing to do it to add ISONOE or AT616 instead of those awful original Technics feet. 

On new Technics the feet are completely different and does not have this problem at all.  

Sorry but precisely because rare but above all very expensive (2 or 3 times more than the Technics 1700) it is absolutely useless to advise them.

AT616 can be used not only under turntables, but under a table platform itself, because those feet (like no others) can support up to 60kg (130lbs) and fully adjustable. Raul has been using them under subwoofers! So you can imagine. Expensive, but very effective device for proper isolation of any component in audio system. I have no idea about OP’s budget, the fact that he’s got a relatively cheap turntables is not a target price. Any turntable (from 10kg to 60kg) at any price will benefit on AT616 Pneumatic feet, so it doesn’t matter. Look at the prices for Stillpoints for example.

Isonoe are much cheaper and designed for Technics

I am using Isonoe, what are you trying to say, have you ever tried/seen them? They can be screwed in any technics as the direct replacement of the stock feet (which is a junk even on SH-10B3 obsidian plinth). For any other equipment (CD players etc) isonoe designed slightly different feet. Everything explained on their site. 

As a dirt cheap alternative every   machinery shop can custom made a metal cones of any size to put under turntable plinth. 

Also i think original technics parts available online for purists, but technics feet are junk even those designed for top models of their expensive plinth (even for SH-10B7) and 100% junk on SL1700 (and mk2 too) just like on any other technics OLD turntable. 

@nandric

I substituted those with AT 636 footers under my Obsidian plinth
and SP 10,mk2 . I assume that chakster’ s are bigger but not
necessary better.

Now when i have the manual for both models i can tell you they are completely different internally as i can see on schematic. So the difference is definitely NOT only the size. The bigger AT-616 (support up to 60kg) has different structure compared to smaller AT-636 (support up to 36kg). Not just bigger spring but entirely different design of pneumatic mechanism inside. 

@nandric i don't want to impress anyone, but at least you should know that The AT-616 support from 10 to 60 kg, look here. 

These type of pneumatic footers can be placed not only under any turntable directly (or dac, cd player or whatever ) ... but also under heavy subwoofers if needed, or easily under some big butcher blocks even if you have more than one turntable on such block. 

The weight of turntable often vary because we're all using different plinth of different weight, some slate plinth are too heavy.   

Great Audio-Technica insulators in comparison @nandric :
AT-636 here
and more expensive AT-616 here

hope it will help to understand their entirely different structure 

 I am convinced that the sceptical review
of the SP-10,mk2 with Obsidian plinth was caused by those
worthless footers.

yes, stock footers are awful
