Micro-Seiki RX-5000 platter question


One of my long term customers passed away and left me his RX-5000.  It hasn't been played in 15 plus years but bearing turns fine, motor runs fine and no audible bearing noise when listening with a stethoscope.  It needs a lot of TLC in terms of the platter having years of grunge on it.  There are two holes and you are supposed to screw the two screws of the supplied handle into it in order to lift the very heavy platter up.  There is almost no clearance between the bottom of the platter and the plinth.  Does anyone know what screws are needed to thred into those holes?  I'm sure they'r emetric but need to get it off to clean thoroughly.  Thanks

@hifiguys you received some very good advice from dover, as expected. As for the Micro gunmetal platters, they ring when not properly damped, so you do need a mat of some kind. Some might call the sound ‘lively’, but with the ‘naked’ platter the table tends to sound a little bright and unsettled.
 

Micro advertised at the time that the platter didn’t require a mat, but to my ears this clearly was a misdirection. The CU180 (and the heavier CU500) copper mats were sold as accessories, but really should have been an integral part of the table. In my experience this copper mat is the only one that effectively kills the ringing without killing the dynamics along with it (as most other mats do to some extend). Without it you won’t be able to hear what the RX-5000 can do.

dover is also correct to be very careful with used samples, but thankfully Micro-Seiki.nl offers exact one-on-one replicas that will be perfectly flat. Not cheap either, but these are quality products. Highly recommended!

You can slip some string under the platter to lift it off - use two pieces either side of the spindle.



better 4 pieces of string to form a square

Dear @hifiguys : I reduce/puts at minimum the platter ringing in my 5000 using sorbothane all around the metal surface in the inside and hollow space below the platter and the mat I used was the SOTA mat along the reflex SOTA clamp. Works fine.

 

Regards and enjoy the MUSIC,
