Subsonics with Grado & Rega Arm
The SME 3009 has many different gradations or varying models(?)but one figure I did find that indicates about what it could be,is that the effective mass for a fixed headshell version 3009(?)is 6.5gms and if it has a removable heashell 9.5gms.So w... 
Subsonics with Grado & Rega Arm
You probably do have a compatability issue with the Rega RB 300 and the Grado Ref.The cartridge resonance for this combination is about 8Hz which is below what is considered the ideal today,around 11-12Hz.I would consider a new cartridge and if yo... 
TWL Weight Mod question
The cartridge is Linn K18 Mk11 which is now discontinued but was a very well-regarded MM and I think that the old Ortofon VMS is showing it up. 
TWL Weight Mod question
I think you misread the post Doug.I have 2 TWL's in operation. 
TWL Weight Mod question
I have just added the paper clip,for tracking weight fine-tuning,and low and behold it works with the Ortofon!It seems just as responsive as the other one modded,resonance around 12Hz,which is more typical.I think it has something to do with the w... 
TWL Weight Mod question
The cartridge for some reason seems to match the Rega arm.I did a search on the Ortofon VMS 20 E Mk11 and a lot of people remember it fondly,I think one of our members Quadophile uses one.It is believed to be better than the current MM's Ortofon p... 
Free Rega Sub-Platter
There are a couple of other tweaks.If your Rega runs too fast(usually around 2%),2 even splices(neatly trimmed) of electrical tape around the sub-platter,widening it and thus slowing the revolutions down, will fix it.If it is too slow,try boiling ... 
Moving Iron Frequency Response
Yes,but what I found with Ortofon is that they normally give frequency response values over 20Hz-20Khz,then a frequency range figure which is different again can be given(i.e The OM series).Here are some interesting specs Ortofon VMS-20 E Mk II Ty... 
Record Damage and Conical and Shibata Styluses
There is still some guy in the States who used to work for Audio-Technica making his own CD-4 Shibata cartridge and selling them to people who still maintain a quadrophonic collection.I e-mailed him about their suitabilty for stereo playback and a... 
Record Damage and Conical and Shibata Styluses
Was RCA connected to the Victor Co. of Japan Ltd. because the U.S patent states that they are the assignee and Norio Shibata the inventor?From what I have researched,it is worth spending the time to align a Shibata type stylus correctly as it will... 
Record Damage and Conical and Shibata Styluses
Yes,I have the Van Den Hul patent somewhere and I will find out.I think it was finally approved around 1978.What I found striking was the claim in the patent that the Shibata profile does not wear out a record after a few plays as a "coventional e... 
Record Damage and Conical and Shibata Styluses
Here is a summary of the abstract to the patent for the Shibata..the idea seems actually brilliantly simple.The Shibata stylus-"a contact surface contour of a shape which is short in the longitudinal direction of the groove and long in the depth d... 
Record Damage and Conical and Shibata Styluses
The patent was originally submitted on March 8 1972 and patented in November 27 1973.Now in talking to a Linn dealer from whom I purchased a Linn K18 Mark 2 cartridge second-hand,he stated quite unequivocally that this cartridge's profile was a Sh... 
What Turntable to buy under $600 ?
What about the cartridge resonance figures Pauly for the comparisons between the Rega,SME 3009 and Mayware.Did you do them?Are you familiar with Paol Ladegaaard's paper on mechanical resonances in turntables? 
Cartridge Recommendation
Stan,To "Riot" was the first move you had to make semantically,in your move at me when you decided that I was an "audio nong" you just had to diss.I have been a riot for most of my life.P.S I saw ya!
