Technics SL-1700 feet

@john421,  are you looking for feet for a SL-1700 or SL-1700mk2?

My first SL-1700mk2 was a rescue case, nearly destroyed by a rap-“DJ”. He took the feet off of it and lost them. Not being able to locate the exact replacement feet, and not very impressed with their design, I set out for a better solution. I took a set of SL-1200mk2 feet and tapped the aluminum foot mounts to accept the 5mm or 6mm thread they use. Since the SL-1700mk2 already has great spring suspension isolation, the SL-1200mk2 feet (which are the only isolation the 1200 has) have to do a much better job, and on the SL-1700mk2, they work, fit and look great. Maybe this will be a solution you can use too. 

That’s for SL-1200mk2+ turntables. The SL-1700mk2 (and 1600mk2 and 1800mk2) have a proper spring suspension of the TNRC platform supporting the spindle and tonearm while the 1200 has a solid hunk of rubber. That’s also why the 1200 feet are better than the others. Add the 1200 feet to the spring suspension and you have as close to perfect isolation as you can get. 

The spring suspension on the SL-1700 is excellent. The mounting should be to the plinth via aluminum brackets if it’s like the SL-1700mk2 which then suspends the TNRC floating base that carries the spindle and tonearm. Since the spring suspension is already giving you plenty of isolation, you don’t have to spend a fortune on feet. 

Looking at photos 11&12 on pic click https://picclick.com/Technics-SL-1700-Turntable-Plinth-Genuine-item-Cabinet-392013998923.html#&gid=1&pid=11
the suspension is the same design in principle. Drilling and tapping the holes for the old foot mounts to accept the SL-1200mk2 feet should be just as easy as on my SL-1700mk2. Don’t drill all the way, because you need to put a screw in the bottom of each suspension tower to secure it to the plinth. I took regular sheet metal screws, #6 iirc, chucked them into a drill and held a flat file to the heads to make them fit through the suspension tower. It is much easier than it sounds. Really, it is.

Isonoe are not designed for any Technics model, only the SL-1200mk2, which is vastly different and inferior to the spring suspended SL-1700 and SL-1700mk2.

(Technics feet are)

100% junk on SL1700 (and mk2 too) just like on any other technics OLD turntable.

Not a very objective statement. There’s more to the story also. The feet are are designed to work as part of a system. It is the whole system that either accomplishes or fails to accomplish the goal of isolation. This comes with varying degrees of success. The SL-1200mk2 for example is for most intents and purposes, unsuccessful at isolating vibration due to its poor secondary and lack of tertiary isolation (sprung rubber feet and rubber chassis) which lacks diversity of spring rates, compliancy and natural resonance frequencies.

The majority of lower end Technics models do much better with only sprung rubber feet and TNRC chassis, thanks to diversity in the isolation system.

Back to the upper mid range, the SL-1700/1600/1800 mk1 and mk2 variants incorporate highly successful sprung suspension and TNRC chassis on simple rubber feet. If you replace those with the better rubber/sprung feet from the SL-1200mk2, you end up with an isolation system that is so successful in its mission that you couldn’t want for more. That is because it incorporates elements with difffering spring rates, compliancy and natural resonance frequencies. Each on its own cannot be as effective at successfully isolation vibrations as the whole system.
