Hi.  I acquired and spent a lot of time on this guy over the last few months. I've installed a Dynavector 507 MK II tonearm and a Dyhavector XVS-1 cartridge.  I read Romy's comments that in his experience with the 8000 the belt doesn't affect the sound.  I bought some of the aramid fiber string and made a belt but have trouble keeping the speed consistent.  Not varying, just dropping down to almost half and staying there.  Bought a $20 "replacement" belt that seems to cause static, which I don't understand.  Now I'm seeing the SF-1 belt, some new, which is fiber.  I don't have a preference, just something that works reliably and sounds good.  I didn't even know the fabric one existed.  If anyone has suggestions, with sources, they are very welcome.  Thanks

 
rom661, Reading what you are saying I do not think that your problem is with belt or with a type of the belt. I do not know what setup you are running and what are your expectations but on this type of the tables the type of the belt is kind of irrelevant at least when the platter has reached the cruise speed. the fact that you report that your platter drops speed in half is indication to me that your suspension most likely not good. the RX-5000 has boll suspension which is most likely has 40 years old oil. Also, if the turntable was shipped a lot or heavy handled then the bottom plate under ball rolling might be warped. each in signal 5000 that I've seen had this problem and you need to reverse the plate and serve new oil. I think the idea to put instead of the steel plate under the ball some kind of contemporary ceramic material would be else not bad. I have written about it in this site in the past, you can search it.
