Post Subject: Schröder & VTFPosted by bernie_f on: 12/16/2009

VTF on all the Schroeders is adjusted by moving the counterweight behind the "bearing" back or forwards. This counterweight is fixed on the armtube by a screw. On the greater Schroeder arms there is also tiny screw on the backend of the armtube to do micro-adjustments by screwing the screw in or out some milimeters (very well thought out!). As a result of all this, VTF can be adjusted with any conventional tool. It should be measured - as always in my opinion - on the record level.When you change VTA on the Schroeders, VTF drifts in very small amounts with changing the VTA, since the string of the bearing adds a llittle amount to the VTF due of bending. When the arm is perfectly parallel to the record surface, the string-force is zero. But when the front of the arm is lowered (string not in a perfect right angle to the armtube) it adds to overall VTF or vice versa.The Schroeders are great sounding arms, and can be perfectly adjusted to find the sweetspot of your PickUp. I would NOT recommend the arms to newbies. They will be fiddling around endlessly. The fundamental "problem" of this arm is, that changing one of the three main parameters (VTA, VTF, damping) changes the two others in small increments too. Can make you crazy if you are a "tweaker" not a "listener"...have a nice day anywaybernie
