The damper, the tension wire and cantilever position

I guess this is not the place to 'delve into' the reasons for the terrible mess sapiens  has got itself into, so I won't.

Your offer to hand over 30 of your cartridges for my LL is very tempting, but having over 30 is already exceeding the bounderies of sanity. Besides, I wouldn't want to have another 30 of them looking to get their revenge. My LL sample has an interesting history, but now with its boron cantilever it's nothing more than a Blackheart with a very fancy dress.....

Having a real difficult time understanding the OP’s question, or point here:

 

Now my assumption is that damper to which coills are ,say, pressed

by tension wire  balance cantilever/stylu combo in  ''all directions'';

left and right and above and below . BUT they also MUST FOLLOW

the GROOVES.

This description applies to many MC carts, and many Audio Technica carts. Not so much to a great many MM carts. 
 

“Damper to which coils are pressed” ONLY applies to MC carts, a very narrow application. 
 

So, are we talking about weakening of the damper? Elongation of the tension wire? 
 

Every cantilever must have a spring force, and a damper. Some styli use a spring and damper in the same suspension (elastomer block). AT uses a tension wire spring and a donut damper ring. Shure used a spring tension wire, and an elastomer block for damping and high frequency spring; Stanton used a variation of this, as did Empire.

Loss of damping over time can occur, and depends on the elastomer compound. In all cases, there has to be a force (spring) to return the cantilever to its neutral position after every excursion forced by groove modulations. A loose damper will hamper this. 
 

I have 163 cartridges, most I have repaired or rebuilt the stylus assemblies myself.

wolfie 62,

Curious that you answer the question about the ''subject matter''

which you don't understand. 

The most MC carts have an cover plate above the genarator but

some are nacked or as EMT by wich the  genrator is visible.

On the generator one can see ttwo srews on both sides. Those are .

I assume , to ''center '' the cantilever. The tension wire is fastened in

the so called ''joint pipe'' (aluminum tube) in which front side cantilever

is  gluead and coils at its back  side.. Those are called ''the moving  parts''..

The moving parts are connected with the generator on which front side

the damper function as a part ''between''. The usual wire is piano

string  fastened at the back side of the generator. At this end of the

generator the wire can''t be reached or (re) adjusted. But one the 

body of the generator there are two srews which are the only pssible

means to ''correct'' the wire. tension.  If, say, the cantlever ''devition ''

is on the left side the screw on the opposite side can be used to ''center''

the cantilever. One can put tjis also ''otherwise'', Say the damper left side

is as function of time weakened so by pressure on the tension wire

one can compensate the weakening of the damper on this side. 

Your other question is about ''generality'' by which you mean ''ALL

KINDS OF CARTS'''. Say MM as well MC. To me this is like

comparing apples with pears. Or to understan MM thread ''stricto

sensu'' in the sense ''not allowed for MC kinds''. But J.Carr proposed

to include OTHER  KINDS in thie ''MM''  thread. 

 

ANTI-SKATE involved in the ASSERTIONS (aka ''premise''). We all

think in the same way:  from premise to conclusions or deduction.

The DIFFERENCE is DIFFERENT PREMISES. In this context

the LOGIC rules: wrong premise = wrong deductions or conclusions,

There is consensus in our forum that  there is no consensus about

anti-skate.

My first test record contained an part between grooves without grooves.

The so called ''blank-side''. To get the ''right skate'' the stylus should 

stay in the same position; aka no skating of any kind= ''REST''.

Van den Hul was the first who, to my knowledge, warned against this

assumption (=premise). I was shoked because I owned my first tonearm

Sony 237 toghether  with ADC 25 . The assumption was ''the hiigher the

price the better product''. According to the Emglish saying: ''I am not

rich to buy cheap stuff''. My Sony had an ingenious provision for anti-

skate designed to work in accordandance to record surface distaces.

Even the stylus shape was accounted for. Curiously ( ?) there was no

''copycat'' of this invention. Ergo : in the GROOVE cantilever/stylus combo

work different as on or at ''blank side''.  Well the their TASK is to follow the

GROOVE. I..E the groove has , so to speak , the ''leading function''.

That is how I got my conclusions.

 

Nandric, y'all spelt too maney thags wrong.
