Turnable database with TimeLine

Syntax said...

Another example, the new Airforce One Turntable from TechDas has 1x contact per revolution with the own motor controller. This seems to be enough to hold the platter speed no matter what is going on. I never checked it but I read from an owner who did the Sutherline Test and it was ok. Personally I believe it because when the Japanese do something serious, they don't make a fault like this.
When timeline has 6 flashes per revolution, it isn't that bad, or?

wow, you are not critical of the AF1 ? As far as speed control, it helps when you use a built in tachometer that monitors and speed adjusts based on record drag. Record drag can vary record to record as I am sure you know...

Well it's nice to know that my previous posting about Tonywinsc claims goes unread or misunderstood.....so I'll repeat it once more before I'm out of here.
The analogy to a car's engine is totally spurious for this is DESIGNED to increase and decrease speed.
Any AC or DC synchronous motor is designed to maintain constant speed.
The Timeline flashes exactly once every 1.8 seconds which co-incides exactly with one revolution of the platter if spinning exactly at 33.33rpm.
If we watch it for 100 revolutions and that 'flash' is hitting the mark at exactly the same point every single time.....we can logically conclude that its speed is constant....UNLESS it can be proven otherwise?
And Tonywinsc has not once...proven otherwise?
It is not possible for a synchronous motor to speed up and down in between the 1.8 second interval yet CONSTANTLY hit the same mark every revolution.

For any scientists who may be reading this Thread and shaking his head in disbelief.....my apologies to you.
And to Ron Sutherland....forgive them for they know not what they speaketh...

Lew,

Henry, I don't think Syntax's post about the Kuzma was so provocative.

Of course it was......
Syntax was apparently observing the Kuzma turntable with the Timeline in action yet he didn't use his iPhone to film this and upload to YouTube (as we know he can do)....which is the point of the Thread.
Instead....he spreads malicious rumours by 'words' only?
But this is his preferred modus operandi as can be seen over the years of 'Raven baiting'?
Thankfully we now have a video of his 'famed' RX-5000 displaying for all to see....an abject and inferior speed maintenance performance.
This video has finally put to rest any desires I might have had to actually obtain a Micro RX-5000.
Be prepared for this damning video of his to mysteriously be removed from YouTube in the near future......?

Studying the video of Syntax's RX-5000 turntable with the Timeline.....I was trying to analyse the reasons for such a poor performance?
Mainly because I had seen nothing like it with any other turntable...belt-drive or direct drive?
How could the Timeline laser move backwards at every revolution and by the third or forth one.....jerk erratically forward to where it originally started?
And suddenly I understood.....here was a perfect visualisation of motor cogging.
This Micro Seiki motor was cogging its head off......spitting and spatting like some rat attached to electrodes?
No wonder Thuchan threw out his Micro motor and replaced it with the VPI one for his RX-5000....and sold off his SX-8000II with Micro motor?
Thuchan has discerning ears and can hear the comparisons to his EMT927 and Continuum Criterion.

And was I the only one to hear the 'sound' on Syntax's video?
I know it's compressed and running through an iPhone mic......but so are mine?
And what about the 'scraping' noise that appears half way through?
As Syntax is want to say....."one man's mountain is another man's valley"....

Halcro, I just rewatched Syntax's video of his RX-5000. To be fair, I think the frame speed of his video camera is interfering with the laser flash increments. I think that is why some laser flashes are not even seen and why the dash appears to change in length. This occurs with my iPhone video as well, but to a lesser degree. I don't know the f/s spec. for the iPhone.

I think the scratching/rubbing sound to which your refer is his breathing. Inhale, exhale etc.

This thread is supposed to be a database for Timeline results and if each submitted video is criticize to the extent that you criticize Syntax's video, few members will be encouraged to add to the database. One of the problems I see with this format is that it is hard to find the videos if the links are added somewhere down the thread, but I don't see how this can be changed now.
