TT speed
Larry, You wrote, ...."at some point slowly moving forward (retarding, in terms of time), then at the top of the arc, it starts to retreat (speeding up)"  I think you would agree that although the velocity of the stylus tip does decrease as it mov... 
Please Help T3F problems
I have no direct experience with T3F, but I am under the impression that it was an expensively constructed upgrade of the original Rabco tonearm.  The Rabco was a straight line tonearm that actually relied upon pivoting to make its way across the ...

You are connecting two parameters that are not related. The stylus tip does not need to know where it is on the surface of the LP in order to reproduce the frequency accurately. It’s essentially a point in space. For any pivoted tonearm, the styl... 
Record Static Charge Affecting Vertical Tracking Force (VTF)?
Shure Corporation published a white paper on Static Charge as it pertains to vinyl, and they actually measured increases in VTF and correlated them with the amount of charge on an LP. I wish I could recall the exact results or find the paper on li... 
SME 309 or SME 3009r?
I was recently consulted privately by someone who had a choice between a Technics B500 with two arm wands, one each for high and low compliance cartridges and with good bearings, and a 3009.  I advised for the former of those two choices, but the ...

Ditto to what testpilot said.  I think you are saying that the two alignment points afforded by some types of protractors are typically separated by 20 degrees, using the arm wand and the pivot as the definers of the angle. But tone is about the c... 
Received The MC2000 Back From Expert Stylus Today
In the midrange, my MC2000 can be uncannily good at conveying the sense you are there at the performance. I hated when HP used the word "holographic", which was then copied by other reviewers who were not in his class linguistically, but "holograp... 
Where did he go?
All kidding is definitely aside.  
VPI Fatboys versus others in its' tonearm weight class.
Ok.   
Where did he go?
200 years ago, and longer ago, was the heyday of the Czars. The vast majority of Russians were virtually slaves to the nobility. It’s a wonder to me that their revolution had to wait 100 more years after Napoleon.

Spindle to Pivot. If VTA tower is centered over the pivot point then measuring to the center of the VTA tower is ok. Measure in the plane of the platter surface.  
Does Furutech lose effectiveness over time?
"Records attract no dust and require no cleaning" Dear Kelly, I beg to differ. LPs develop significant static charge on their surfaces. And static charge attracts dust and holds it until the charge is dissipated. There are several causes, such as... 
VPI Fatboys versus others in its' tonearm weight class.
If you find a good match to a cartridge, it will sound fine.  Maybe some other VPI fans here can suggest a good choice. For me, unless the tonearm is grossly bad in terms of design and build, the important thing is that match to a cartridge.  
VPI Fatboys versus others in its' tonearm weight class.
From skyscraper’s photos and Dover’s post, it does seem that the tonearm is "surface-mounted" on the plinth. Apparently there is a wide diameter hole that can’t be seen in photos, which permits the vertical shaft of the VPI tonearm to penetrate th... 
2020 update : JC Verdier La Platine
Thanks for the correction.  I wonder what is an NSM.  If you push on a Minus K, it does not behave as if primarily spring loaded, which is to say that a spring will exert a force directly proportional to its degree of compression or extension from...
