The damper, the tension wire and cantilever position

@edgewear It was a sad day when Kilian Bakker informed his UK Customers he was not to offer his services direct with this Country.

I do have work associates who live in Holland and Eastern France nr Belgium, so a opportunity to create something may be able to be organised in the future.

It was Kilian who was the first to inform me about airborne Metal Particulate contaminating coils, and even shorting them, when the impact is catastrophic, it can pretty much become a channel loss. This is not an issue with a particular Cart’, it has potential to commence occurring from the day a New Cart’ is put to use.

At present I am very infrequent with using my preferred Cart’, (rebuilt by Kilian), when put to use, it is approx’ one Albums Side before the Damper seems to develop a elasticity that performs with an attraction, and a good hour of use before the presentation is seemingly back to its earlier self.

 

Dear edgewear, I am  willing to exchange 30 of my cartridges for your Lapis

Lazuli. You will than get 60 and I ONLY 30 cartrideges. The inventor of the

whole Kiseki story was aware of the problem. For thiese who could not

afford  Lapis Lazuli he produced the so called ''poor man Lapis Azuli.'. Aka

Black heart . The ''on;y'' difference being boron cantiler and wood instead 

of diamond cantiever and Lapis  Lazuli jewel, Only available in Afganistan,

I am not sure  if I should inform youa bout this. But ''at present'' as Marlene 

Ditrich stated wondering why American women are so poorly clothed

''at present one can get decent clothes for ony 100000 $''

My assertion was ''based o induction''.  Like sky is the limit in America

so everyone can become rich in America, I as mentioned I spend a fortune 

on  my cruked cantievers so the only one with such ''deviation;'' is my

Kiseki Agaat. This is common practice at present. Becouse Russia 

invaded Ukraine all European country expact Russian invasion. So all

of them increased military spending and souranded Russin Nord borders.

But meanwhlle there is invasion   from the oppistww side with imigrants

from all Africa an midle East. Withouth any weapons. So tehy know how

to defend thesemlf from Putin but have no idea how to defend themself

from the imigrants. I fear USA has similar problem?

l

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.
