Doh!! I must really be going nuts, "disengage anti-skate" thank you, thank you. If I ever have a problem with a unit powering up, I should check to see if the cord is plugged in, LOL.
I just wanted to know whether VTF should be measured ON the playing surface or OUTSIDE of the playing surface...Jameswei with his Graham made an interesting point.
I believe Doug fully understands my query (and anyone else with a Tri-Planar). I have many cartridges that I swap on a regular basis and setting VTF "properly" the first time will allow me to enjoy more music with less tweaking, ie. fine tuning by ear...
Harry :D
