I have heard of a Tannoy badged Micro Seiki so I think there is a fair chance it is made by MS. I did have a list of all the TTs made by MS but can't seem to find it. Post pics and I'm sure we'll be able to say if it looks like an MS. I have an MR611 which would be similar.
Of course, if it sounds great then it doesn't matter so much who made it!
My System: Micro Seiki BL51 Turntable, Stax UA7 Tonearm, RCM Sensor Prelude Phono Stage, Ortofon MC15 Super II Cartridge, Rotel RCD865BX Cd Player, Melody I34R (Astro Black 40) amp and Osborn Epitome Speakers.
