| Tracking error distortion audibility Dear Raul, a very interesting point. You are right - the effective mass does indeed increase when you move the cartridge away from the pivot/bearing. The position of a given cartridge does have some influence on the resonance frequency. Whether it... | |
| LP eccentricity, spindle hole center,The fix?????? 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. | |
| LP eccentricity, spindle hole center,The fix?????? 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 samp... | |
| Tracking error distortion audibility Dear Raul, the Dennes paper is very good indeed. Its a great classic since 2 decades. However - it too does only deal with the "2nd" geometry. Baerwald, Loefgren, bauer, Stevenson etc. - this is all about the geometry of the stylus in a given tone... | |
| Geometry for pivot tonearms - calculation errors?? Dear Raul, I agree with you - this is a complex subject. What I am aiming here is the difference between the basic tonearm geometry (for the individual tonearm) and the geometry for the interaction with a stylus (Baerwald, Loefgren, Bauer, Stevens... | |
| Geometry for pivot tonearms - calculation errors?? Dear Johnbrown, thanks for the input. A good start for this thread.And the above mentioned links are useful indeed.However - this is all included in the G.F.Dennes Tonearm Analysis and Summary. These are all about the different options in calculat... | |
| Verdier Upgrade Kit Dear Ledoux, the kit is NOT available yet. However - the asking price is not really inexpensive..... to say the least. The kit contains of simple mechanical parts which do not involve any significant labor or parts costs at all. The principle is f... | |
| Tracking error distortion audibility Dear Raul, you asked:"Dear friends: Anyone of you can corroborate what I posted here:www.ispexperts.com/BaerwaldLof...Dertonarm: where can we corroborate what you posted? "Where to corroborate my postings on this topic ? In every decent (high-scho... | |
| LP eccentricity, spindle hole center,The fix?????? 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. | |
| 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 increas... | |
| Tracking error distortion audibility Dear Rauliruegas, all I did was displaying the geometrical facts. I don't know why you are so mad about this and why you have so many problems accepting these technical parameters which were and are used in analog playback in the past 6 decades.Ag... | |
| Tracking error distortion audibility Dear all, to my knowledge the 9" and 12" denomination was introduced by SME with their original 3009 and 3012 tonearms (hence the names...3009 and 3012). Ever since then 9" and 12" is used to describe tonearms which do have an effective length aro... | |
| LP eccentricity, spindle hole center,The fix?????? Dear Kftool, those 0.284 inch do equal the 7 mm in metric world. That is indeed the standard.Thank you for setting this straight. | |
| Tracking error distortion audibility Hi Axelwahl, you should consider the MINT LP tractor. If you settle for one specific cartridge right now, it is well worth the investment - especially with a SME V. It does provide very good results and is easy and fast to use. | |
| Tracking error distortion audibility Dear Axelwahl, all you are asking is explained during the course of the thread mentioned. You either have to keep on reading all through that thread or send me a direct email.This is too much, to repeat all that was written in March during that so... |
