The main bearing with the screw-in bottom-cap originally had a plastic thrust-plate in the bottom. The ones I have seen had completely gone to pieces. This both reduces the efficiency of the bearing, and drops the platter to where it it can be rubbing on something. I believe the original was about 1.5 to 2 mm thick.
You might consider a Denon DL-110 cartridge.
Yeah I know, mine was also completely shot to pieces inside the cap.
In fact you did suggest me some time ago to use a kind of teflon sheet (thanx).
I,ve managed to fabricate a thrust-plate out of a teflon like material called: Werkstof S (or: HMPE 1000).
It seems to do the job well, because the platter is turning featherlight by now.
And I,m using a stethoscope (idea from a member from an Dutch site).
which is fantastic for hearing minor imperfections in the bearing adjustment (stethoscope was only 8 euro,s new including transport
), and I don,t hear no strange sounds at all.
By the way, there,s a guy on ebay.com who,s selling thrustplates including TT oil.
