Mine needs to be dialed at twice the AS force. And the arm floats perfectly when AS is zero. Make sure your TT is perfectly level before adjusting AS.

TT is perfectly level, but I will check again how much AS is needed to keep the stylus from gliding towards the spindle. I assume you also use a CD or blank vinyl to check this?

That method is not the best, imho.

I use the lead out wax, and let the stylus glide in between the lead out tracks. At roughly the same speed. It turns out to be a very good setting. Never had any AS related issues.

On the plx1000’s dial, it’s rougly 2x de VTF with ellipticals. And 2.2x with line contacts.

My PLX-1000's build date is August 2018. Antiskate dial is definitely off by a factor of 2x-2.5x. Even Pioneer's promotional photos show an AS dial marked from 0 to 6. That just can't be right.

I've had many turntables on which the arm would drift outward even with the AS set to 0. My Technics SL-1200MK2 did that.

Sorry, I can't follow, between the lead out tracks? If you mean the run-out groove, how would that go? On a spinning record the stylus will be caught by the groove, doesn't it?

@all
I just tested with a blank CD and my anti-skate seems to be engaged all the time. At 1,8gr VTF the stylus will move to the outside of the CD even at zero anti-skate! At 2,5 gr of tracking force it'll slowly move towards the spindle at zero AS, adjusting the AS to just below 1 and it'll stay put.

Double the VTF value (which seems to work for many) and the stylus literally flies off the surface...

Yes, in between the lead out grooves. You land the stylus between the groves, and adjust the AS until it skates inwards without falling into the grooves. (it does fall into the groove at the very end, obviously). Now, this is just an Aproximation. My preferred aproximation method.

The blank CD is also an aproximation, and is not my preferred method, but not by any scientific means. Just personal preference, since you've got no lead out grooves to use as an inward speed reference, AND, the CD is made of a different material than vinyl records, yielding a different friction coefficient and consequently a different skate force.

From my experience, super-duper-precise AS is overkill. Any aproximation method will yield good results. As long as your stylus stays in the groove, the cantilever looks straight against the body, and no apparent distortion or channel imbalance is heard, you're good to go.

Cheers,
Luis

I tried the blank CD thing and got very different results. I have more faith in the vinyl runout test method.

I'll try the runout test, maybe that'll show different result for me as well.

It's possible I've completely misunderstood the way that anti-skating is supposed to work for years. But I always thought you wanted to adjust antiskate so that the tonearm was stationary on a blank record, not moving inwards?

Is my idea as well, but slightly skating inwards is probably okay as well.

@all
So, I just tested the method with setting the stylus down on the vinyl between the runout groove. Even at zero AS it will pull outwards!

So, my anti-skate is always engaged, even at zero AS and apparently with enough force to pull the stylus outwards at 1,8gr VTF.

:shock:

You should have that checked out.

Got the PLX-1000 today... I got lucky... AMazon shipped it in a box upside down, but no damage was noticed.

The platter is flat, there is no play on the arm bearings and there is no motor noise... Yeah! The sound with my old Shure V15 Type 4 is a lot better than my Sony PS-X7... The bass is tight, the image is rock solid... I did notice that the Sony has silkier highs though. The anti-skate was a tad off. i had to set it at 2 grams and the cartridge was set at 1.5 grams.

Overall, I think the Pioneer is a winner.

OK... I came across my first issue with my PLX-1000... I am having a ground problem. When I press the Start/Stop button, there is a momentary hum coming out of the speakers until I release the button. When the PLX-1000 is playing, I do not notice the huim. When I increased the volume by 10dB above what I normally listen on my amp, I can hear a background hum. I checked the cartridge connection and the ground wire is hooked up properly... Any ideas?

It is a Shure V-15 Type IV with a new JICO Stylus...
