In Reply to: Re: Help with VTA on a Thorens TD-125MkII posted by bangsezmax on August 1, 2005 at 10:33:07:
You seem to have lots of experience with the Thorens. What have you noticed about the antiskate device? Mine seems to be off. I have to over apply it. Sometimes I'm not sure if it's doing anything. Do these things get weak over time? It's the magnetic one on the TP16 Mkl. I'm using the HiFi news test record to help set the antiskate adjustment. Thanks

I imagine they could get weak over time, but I don't know for sure. I can't personally attest to any knowledge of the magnetic properties of the material (ferrite?) in question. That said, anti-skate settings aren't quite as critical as azimuth, alignment, VTF, or VTA. If you're getting a good idea of where to be with a test record, I'd just leave it at that.I kinda wish that Thorens had used the TP11s more than the 16s -- I think both the VTF and anti-skate settings are more "true" on the 11s. But I'm not about to transplant a TP11 on my 160 or my 126.
Yes, you're right. My VTF adjustment is not accurate. I just set it using the counter weights. To the other guy, who started this thread, make sure you have a scale to check the VTF.
One other note -- the tension on the wire for the VTF setting can be adjusted. The little tube over the counterweight has a hole in the back of it. Look in there and you should see a threaded sleeve. In that sleeve is a threaded nylon screw that can be moved to increase or decrease tension (the crimped end of the wire sits in the middle of the screw, so you may have to rig something to move it -- I used a pair of tweezers).So if you have a scale (assuming your tension line isn't binding anywhere as mine had been), you could adjust the VTF setting so that it reads accurately.
Again, this is why I love the Thorens -- it's as if they knew their tables would still be running in 30+ years, so everything can be easily recalibrated if need be.
Yeah, I just bought one of those little digital scales on Ebay (I think it was ~$22 with shipping). I've been futzing around too long trying to guesstimtate 4-5 grams for 78RPM carts on tonearms that don't adjust above 3 grams.
