Thanks for your input as well.What digital scale did you buy?I was wondering about this subject myself.
I still periodically check my azmith and fiddle with the counterweights,and don't have a digital scale yet.
So with your scale you were able to determine that the
VTF would change alot? If so I'm curious .How much would it be off?
I also have extra info on the set up of this arm that an audiophile supplied to me.I can quote some of the info he gave me.
"Since it is a unipivot,I think it is important to make sure
the table is level before any arm adjustments.
Dealing with the weights will seem odd at first ,but once you get used to the design,it all makes simple sense.
Remember: Azmith is everything! If azmith is not right,the arm will not be properly balanced.It takes a while to get this right,but,take your time and observe the cartridge while on a record,and,also as the cuing lowers it to the record.Their is a sonic benefit to using as much weight as possible,and locating it as close as possible to the arm body.Weight your cartridge and use the chart to determine which weight to use.I got the best sound by not using the small counterweight at all because it enabled me to use the 2 heaviest weights closer to the pivot.This is tricky though because when you move the weights to adjust tracking force,they may have screwed up the azmith because of the eccentric holes.For your initial setup,you probably will prefer to use the small counterweight to adjust tracking force.It is much easier:Twist the eccentric holed weight to adjust azmith,then slide the small counterweight to adjust tracking force.Morch talks about figuring the tracking the tracking force by counting how many dots the weight has passed,but that is so confusing and imprecise that I can't imagine setting it up without a stylus force guage.Also they never say a word about the fragility of the arm,but I think it is a good idea to grip the body gently and lift up slightly to disengage the bearing point while moving the weights or removing the arm tube."
I hope this hepls for you and others who may have a Morch Arm for setting up.
I will be getting a new used cartridge after the 1st of July
the Grado Reference Cartridge,with my VPI MK3 so I will be
starting the whole process all over again.Take care and Happy Listening
