^ there has long been a presumption that Micro Seki was involved in the development and assembly of some of the high end Sansui turntables. The SR-838, 929, XR-Q5 and 7 at least, all have design elements - and even parts - taken directly from Micro models of the time.
With high-end turntables beign a rather specialized area of hi-fi, Sansui chose to consult/contract with an outside firm possessing the expertise needed to build the top models in the line.. The notable similarities are less obvious in the lower range models, and perhaps those were done with the assistsnce of a different contract manufacturer. I believe the same sort of arrangement was made for the Sansui reel to reel units and their more advanced cassette decks as well.
Clealry, Sansui's primary in-house design expertise was in amplifiers and tuners. They also demonstrated serious engineering skill with their development of quad, though that effort was largely unrewarding for the company.
Great resource...thank you for taking the time to post...Yes, the boards are marked Sansui as with any of their gear, however development of the design was very likely assisted by Micro-Seki. Most of the major Japanese hi-fi manufacturers made arrangements at one time or another to contract with outside companies to assist in the design of specialized components like turntables and open reel decks. Some even had certain compinents - audio program timers for example -manufactured under contract.
Very seldom was there any actual indication of the identity of the outside vendor that consulted on the deign, or made a unit under contract for another company. There was a large network of contract manufacturing companies in Japan as well, there is a very interesting accounting of this at the Vintage Knob:

It's a long thread, but gives some iinsight on how this all worked.

I have been trying to enter this but I get 404 message , page not found .
Any ideas?
Yes. There are pics somewhere in this forumDid anyone go with silver feet on their 636/838? Pics?
Weird. I can't find it, but I'm almost certain someone with a 636 put on the silver feet.Did anyone go with silver feet on their 636/838? Pics?
