LP eccentricity, spindle hole center,The fix??????

Dear all, that standard for the center hole was made in late 1940ies when the technical/mechanical standards for the microgroove longplaying record were set.
Those standards were precise numbers.
The problem is poor quality control, the ever increasing need for cutting production costs and too little care in the manufacturing process.
Companies like King Records / JVC Japan and several of the smaller dedicated record companies did always present LPs with very precise center holes. Today the LP-manufacturing is such a small segment of the audio/video market, that this (we...) and its (our..) needs are of no interest at all for the industry.

Dear Jlin, you are right - very often the two sides do differ in their eccentricity. In that case the "alignment" has to be done for each side individual.

Dear Dertonarm: Where we can find those standards on the subject?

Now, the " perfect center hole " standard when is achieved give all of us an immediate quality improvement, it does not matters which analog system we own.

is there a " road " for the recording industry can fulfil with that standard? who is the institution that have to control that that standard be fulfil/realize by the LP manufacturers? how anyone could " force/compel " to the LP manufacturers to do it?

We are paying a lot of money for new LP's that are really bad/wrong in its overall quality.
I don't know others but I'm willing to pay an extra " fee " for that " perfect center hole " standard, no doubt about: that makes a difference for the better.

We all here are commited to improve the quality perfomance in our home systems but I can see that for many of us that is not really a priority because in more than one ocasion I bring this subject with receive almost no " eco " to make and take actions about.

I consider you a serious man on this and other subjects why don't start ( you and me ) or take some actions about, let me know IMHO we need to do it like a " group ", this is not a " fight/war " for one person.
What do you think? or you think it will be " futile " ( like you say. )

+++++ " is such a small segment of the audio/video market, that this (we...) and its (our..) needs are of no interest at all for the industry. " +++++

well, remember that we ( the customers ) are part of the industry and not only that but that industry " lives " thank's to us not to them.

regards and enjoy the music.

Dear Raul, I agree. But the only part of the market we have SOME buying power is the specialised audiophile LP market. And even here - take the infamous Classic Records 200gr issues which were certainly plagued with pressing faults and warped samples - even with LPs which do ask some serious retail prices, we seldom get the excellent and careful pressing quality we ask for and deserve to get for our money.
I am collecting LPs since the early 1980ies.
There always were certain companies showing great care in what they released - excellent quality control. JVC Japan, King Records, for a long time DECCA and EMI (at least in their classical department...).
Today maybe we could put some "pressure" for quality on Classic Records, Speaker Corners etc.

You are right - we should try.
We all.
A small group is not enough.
We would need something (something like...) like the international boycott movement which eventually helped overcome apartheid in South Africa in the 1980ies/early 1990ies. That was a display of positive buyer's power (at least here in Europe).

I think the best way would be if Classic Records and all other audiophile record companies would just start having all their LPs pressed at JVC / Japan.
That would solve all our headaches.
I am in.

Dear raul, I don't know whether the old Microgroove Longplaying Record standards can be found anywhere on the web (but I believe so). I have them in the old printed papers of AE Anthology and Wireless World.
