Mistracking zyx after hibernating?


After about 6 months of rest, my Zyx 4D gold now breaks up on some piano notes and vocals. I had about 250 hrs on it when last played and it was tracking perfectly. I'm pretty sure that it sounded perfect the last time i heard it.

It sounds quite similar when it had less than 20 hrs on it. I haven't touched the tracking force (1.9 g) since then. Tonearm is SME on a michell deck.

Is it possible that it would need some breaking in again? Anyone with the same experience? I'm getting a bit Impatient and would really appreciate some input and reassurance so i can get some sleep again.

thanks in advance for your responses

I don't know that particular cartridge that well, however, ALL parameters of a good cartridge setup must be proper or the setup is wrong. Recheck overhang, azimuth, cartridge mounting, as well as VTF. The next step is to send it back to the importer for checking and possible repair. It could be that the suspension just hardened over time.
This has happened to me before, you just have to break it in again with more vtf.
Bnrlaw,Stingreen,Storyboy,

I did check the vtf and it was still 1.9 g. I have some particular records which I use to check tracking and they are pretty quiet but i'll let them go thru an RCM again.

I'll double check the other mounting parameters and will let you guys know.

BTW, I forgot to mention that I've been using an electric room dehumidifier. It's been raining here frequently and I'm getting this funny smell in my room so it's been on twice a week. Could this possibly affect the cart suspension?

I'm also thinking it could be the suspension firming up again after a bit of rest but as I said I'd rather hear your opinions and experiences.

Thanks again,
Got a Cardas Sweep, and Burn LP?
Run the burn in tracks for maybe 15 minutes a track, and then more importantly, run the Demag sweeps.

What gauge are you measuring tracking force with? ZYX is very sens. to even the most minimal of adjustments. Don't just use a Shure scale. Get a nice digital guage.
Make sure your gauge is accurate to a tenth of a gram (preferably to a hundredth) and increase tracking force to 2 gms. and let me know. My ZYX sometimes mistracks at 1.9 but i have never had it do so at exactly 2 gms.
