Anti skate and tonearm damping query
Axel, the often cited law of friction by G. Amonton (who kind of re-discovered it 2 and a half centuries after its original "inventor" Leonardo) as the main "law" being the skating force in phono playback assumes, that the bearing of the tonearm i... 
Anti skate and tonearm damping query
Of course my idea is wrong. But that is always the case.After we have agreed upon that and set it aside, maybe someone is willing - or not..... no problem (at least not mine) - to visualize what is actually happening aside from dogmas, simplified ... 
Anti skate and tonearm damping query
Dear Doug, lets not mistake the torque tension force (which is indeed a result off the offset angle at the headshell) or the J-/S-shaped form (featured on tonearms with detachable headshell) common on most pivot-tonearms (and seldom addressed....)... 
Anti skate and tonearm damping query
Dear Stan, you are of course right. We have seen - and still have... - MCs with VTF around 1.2 to 1.5 (v.d. Hul among others). MC do NOT have ad decretum lower compliance than MMs. The skating force is - among others - a result of VTF, offset of t... 
How do I match a stand alone motor with a stand...
The VPI HRX or the standard VPI TNT V - motor together with the (I think ) indispensable SDS are a sure bet and will suit all platters if not the ones with outstanding diameter. Sidssp gave the formula - it always a function of the RPM, and the tw...

Newton would smile.....Again Nsgrach - your simplified model does not meet reality.It is obvious and a simple fact that the skating is altering - ever seen any skating in the zero point ? The offset is changing - and so is the amount of skating fo... 
Anti skate and tonearm damping query
Nsgarch explanations are based on the original patent description of skating force and the anti-skating applied. And its too is not a matter of MM-cartridges vs MC-cartridges. Their different basic mechanical characters do contribute some details ...

Indeed - God bless america.Especially so in our troubled times.Thanks to him, that not all americans always go for the most simple model in everything......In this sense - good luck to Nsgarch too. 
Anti skate and tonearm damping query
Skating force is a result of the offset of the polished area of the stylus in perspective of the groove wall. During the journey of the tonearm cross the record side this offset becomes zero 2 times - the zero tracking error point - and is dependi... 
Who needs a MM cartridge type when we have MC?
Great thread Raul !Unfortunately I do not have the time to read it from cover to cover, but I had several impressive experiences with the venerable AT-180ML back in the early 1990ies.I even modified 6-7 samples (glued the cantilever-assembly fix i...

In general - "skating force" is not linear. It is general with modern styli much less than it used to be in the 1970ies. Several respected tonearm designers (Pierre Lurne, Mortensen, ...) do recommend not using anti-skating at all and for good rea... 
What is the chain of importance in analog system ?
Look on the used market. A suggestion of a great combo in that price range ?Well - put (buy...) together the following on Audiogon (will take you 1-2 months only):- Phonostage: Sonic Frontiers SFP-1 signature or Phono One - $700-1k- tonearm: Graha... 
Tonearm isolated from platter in separated tower
The TNT is suspended from outside generated mechanical vibrations by its suspension. The "new" tonearm platform is not.Generally spoken it is not a good idea to isolate the tonearm from the suspended chassis.The TT now is suspended - the tonearm i... 
What is the chain of importance in analog system ?
Usually I do not like the term "chain of importance" but it is tempting nevertheless......Based on my 3 decades in high-end analog audio:1) the phonostage - all the more if a LOMC is used2) a rather close 2nd: the TT3) much more important than the... 
Graham Phantom vs. Phantom II
Gmorris, please read my initial statement: the effective mass is not DETERMINED by the distance of the counterweight from the pivot.There are a lot of tonearms - past and present - which do feature different weight counterweights to match differen...
