alec what do you call tube axis ? (the tonearm tube ?)
vlamofoon, i took the pimpel from its axis, it is in very good condition, not falling apart. Concerning the screw you are mentionning, it is unharmed but quite loose...do you think we're on the good track ?
The screw should feel locked snug in place if you try to turn it. If you are shure it's quite loose, I think its preset-hight is changed, and thus affecting calculated pressure on the steuerdimple.
Proceed as following, but take in account that what follows is a tricky procedure.
*unplug the turntable from the mains AC*save guard your cartridge-needle!
*note the original place of the set-screw (you can use the cut in the screw-head as a
mark to remember
*Turn the set-screw one full turn (360) degrees counterclockwise.
*Remove the platter.
*Engage the startknob and start turning - very slowly! - the motor by hand clockwise Remember: never turn the motor/platter counterclockwise when manually rotating with start- or stopprocedure engaged!
Now watch carefully the movement of the tone-arm if the movement improves.
You may repeat this procedure but be aware of the tricky part: if you feel at a certain moment that the resistance of turning by hand increases - compared with before - the moment the yellow-coloured command-wheel engages the main-leaver wich pushes against the steuerdimple: immediately stop turning the motor and turn the screw back to its former position.
That is why it is so important to keep track of the position of the screw everytime you turn it.
