Dertonarm:
you said
If however the user does wish to align the given tonearm exactly to the geometry (especially the offset angle) the tonearm was designed with, then knowing the P2S and setting it precisely (IF possible ...) is important.
Important only if one wants to avoid an additional breakdown torque and thus another source for skating force in a pivot tonearm with a fixed offset cartridge mounting.
With tonarms like the Schroeder, Reed or Talea however we won't run into this problem at all.
Didnīt you suggest starting an antiskate thread?
But since you have brought the subject up, in what way do the Reed, Talea and Schroeder differ from other arms?
The Talea and Schroeder appear to have a facility to alter the effective length,(as does any other arm with a slotted or movable headshell) and they have a facility to alter the headshell angle. What is the difference between this and altering the angle in a normal headshell?
The Reed has a normal slotted headshell except for the model with its little azimuth adjusting device.
Whatīs the difference? I would honestly like to know.
And I am intrigued to know what are these mysterious additional breakdown torques which the above arms donīt have.
Unless you can explain where else it comes from, the only torque acting to rotate the arm inwards is generated by forces acting on the stylus in reaction to downforce and friction. More downforce, more friction; more friction, more inwards torque. No downforce, no friction.; no friction, no torque.
Using more downforce doesnīt make the inwards force disappear, just that the force acting downwards is enough to allow the stylus to track without distorting. The imbalance of forces on inner and outer groove walls hasnīt gone.
John
