Triplanar Question??


Hi there,
I am searching around to see if I can get some advice on where to approxiamately place the anti-skate weight on the bar when in use with a ZYX Universe cartridge.

Is this just something I have to experiment with or have folks found the right place to set the weight in order to track correctly? Any light shed on this subject would be most helpful.

Cheers,
Peter

Ralph,

If you're using a UNIverse/TriPlanar, do yourself a favor and try the O-rings method instead of the metal weight (as linked in my first response above).

Assuming you've got VTF set right (just a couple hundredths of a gram above mistracking) reducing antiskate will sound like a component upgrade, seriously.

Stltrains,

Last night I played at 1.88g, but that really doesn't tell you much. My optimal VTF changes daily with the weather and yours does too, and they're unlikely to be the same. The cartridge is so sensitive it can change in mid session just from warming due to being played. That happened when Raul visited last year. I had to adjust VTF after a two hour dinner break. The cartridge had cooled off and the bass was weaker. Adding .02g brought it back.

Hot/humid weather = lower VTF
Cold/dry weather = higher VTF

FWIW, until we reached the 1000-1500 hour mark our ranges were about like this:
- Winter: 2.05-2.15g
- other 3 seasons: 1.91-1.98g

With more hours on the cartridge our optimal Summer range is now 1.82-1.94g. I won't know if the Winter range has also shifted until it gets cold.

There is no way to do this except to do it yourself, by ear. My best advice is this: play 2-3 sides to warm things up. Then reduce VTF in small (~.02-.04g) increments until you hear faint mistracking on dynamic peaks. That's your mistracking point, which will vary with conditions. In every condition, however, optimal VTF is ALWAYS about .02-.04g above that.

Doug your explanation is top flight. thanks for your input on universe its much appreciated.
so Doug
your seasonal VTF
is that with Air Conditioning?
if it's any more humid down here in New Orleans
my tracking will be below a gram ;-)
