TESTING TONEARM FRICTION FOR THE SL-1200 MK2,3,4,5,M5G
This is probably useful for any audiophile tonearm. Check arm bearings
for play by moving arm about.
There should be no click clacking when you do this.
If you found play in the bearings, they can be adjusted. A tool first
needs to be made to unlock the outer ring that holds the adjust screw.
I have yet to find such an after market tool. But often, you can loosen it with a small jewelers screwdriver. Hold the screwdriver against the slot of the locking ring and tap in the direction to rotate the ring counterclockwise. More often than not, the ring will loosen. Now you can loosen the center bearing screw. check for play. Tighten the screw until the play is just zeroed out. Now re lock the outer ring and recheck the friction using the procedure above.
