What is the effective mass of the Jelco 750 tonearms.

The effective mass of the Jelco 750D 9″ tonearm with the standard headshell but without cartridge is 13.48g.

Here is correspondence from Jelco, Haruo Uchida/Sales Manager

SA-750D effective mass is 13.48gr without cartridge( effective mass is 19.23gr with 6.5gr cartridge). We think that the higher compliance cartridge is usable to SA-750.

The standard HS-25 headshell weight is 12g. The economy HS-50 headshell weight is 9g. So it is possible to further reduce the effective mass by using the HS-50 headshell.
