Help with used TT choices: Music Hall vs Thorens
Hi, Dakajoba; is the mmf-7 turntable the original mmf-7 with the aluminum Pro-Ject 9 tone arm or the upgraded version with the Pro-Ject 9c or 9cc tone arm? Depending on which tone arm is included it would make a difference in what the turntable is... 
How important is Cartridge Overhang? Need help
Hi, Wilson667, have been gone this weekend or would have responded earlier. Sounds as if the tone arm MAY have been redesigned and the specifications have not been revised to reflect a different effective length of (perhaps) ~237.5mm. That's assum... 
How important is Cartridge Overhang? Need help
Hi, Swampwalker; pivot to stylus distance is not really variable with the Pro-Ject 9 series tone arms. The headshell was designed such that installing a cartridge with typical mounting holes will put the holes at about the midpoint of the headshel... 
How important is Cartridge Overhang? Need help
Hi, Wilson667; hopefully things all work out with your Mint protractor. What is the distance from the vertical tone arm pivot to the center of the headshell slots? You should get something around 220-221mm if the effective length is correct at 230... 
How important is Cartridge Overhang? Need help
Dan_ed; I would also consider that the Mink protractor may not be constructed correctly. If the wrong parameters were given or used to set the markings on the protractor that could also account for the problem trying to use it with the Pro-Ject 9c... 
How important is Cartridge Overhang? Need help
Hi, Wilson667: A difference of only 1.0mm should not prohibit you from adjusting the position of the cartridge in the 9cc tone arm headshell to align to the Lofgren A/Baerwald geometry. The headshell slots have enough play forward and backward fro... 
How important is Cartridge Overhang? Need help
Hi, Wilson667; the first question (just to be sure) is what are the spindle-to-pivot and effective length distances that your Mint protractor is designed to accomodate? The second question is what is the distance (measured as best you can) from th... 
Almost set up
Hi, Fred: having the tone arm horizontal with the surface of a typical 140-150g LP is a good starting point. The tracking force (VTF) should be set in the middle of the recommended range and yes, use the centerline of the tone arm tube for sightin... 
STP distance. Is it critical ?
Hi, Nandric, as to the different spindle diameters, if you're familiar with the DB Systems protractor, which uses a set of overlays to find correct alignment, a similar setup could be made that incorporates both spindle diameters found on turntabl... 
STP distance. Is it critical ?
Hi, Nandric, your use of Quine's argument is appropriate. The process of cartridge alignment can be as complicated as we make it but what is needed is an elegant method that considers a wide range of tone arm and cartridge combinations. From W.V. ... 
STP distance. Is it critical ?
Hi, Nandric, I wasn't addressing anyone in this thread specifically, but I do think that talking about a range of tracking errors will help to clarify (and subsequently simplify) the issue of cartridge alignment. The endless debate over the "best"... 
STP distance. Is it critical ?
There is a range of tracking errors that sound similar if not identical. (I would admit that with certain vinyl setups the differences may be more noticeable.) To provide some perspective: Given the gamut of alignments, including Lofgren A (Baerwa... 
STP distance. Is it critical ?
Hi, Bpoletti: good description, and I appreciate that you put 'improper' in quotes. But worst case tracking error is relative. It's a matter of choice as to where along the path of the stylus that the listener hears the faint trace of distortion. ... 
STP distance. Is it critical ?
Smoffat, making a couple of assumptions about the tone arm you can see what the results might be by using the calculators available at VinylEngine. Let's assume that to set up for Lofgren's A (Baerwald) alignment with an effective length of 235mm ... 
Azimuth and the Fozgometer
Dan: Nice! The Talea is a unique tone arm. It would be great if more tone arm designers and manufacturers began treating arm height and azimuth adjustments with the same importance as they do tracking force (counterweight) adjustments. With so man...
