RE: Question




4.3 seems to back up my point.

"One myth that I have heard repeatedly is that to get the total effective mass, you must add the tracking force to the normal effective mass. This ^^^would be true^^^ if and only if you got that tracking force sim-ply by adding a mass ^^^right to the cartridge^^^...."

Until proven otherwise I still say if you add weight directly above the diamond, the weight (in grams) is added (directly, without reduction) to the effective mass of the arm for purposes of calculating the resonance frequency.

Adding a weight, such as the one pictured, where the weight is not directly above, but slightly behind the point directly above the diamond, then math would have to be done to determine what percentage of the total weight is added to the effective mass of the tonearm/cartridge system. Being close to the end of the tonearm makes me think that most of the weight is added to the effective mass.

Now if I turned this weight around so that some of the weight extended beyond the diamond then it would add more than it's own weight to the effective mass of the tonearm/cartridge system. That is to say, if 1.5 grams (of the 3.5 gram piece) were sitting beyond the diamond, that 1.5 grams would add more than 1.5 grams to the total effective mass of the arm. The part sitting behind the diamond would add less than it's own weight to the effective mass but not by much.

Sorry about all the words, I hope it's not too muddy. :-)
