Today I have meassured the resonance of the above combination with a (analog) amplified Voltmeter and a test record. The result was 8 Hz.
The mass of the Denon 103R is 8.5 g, the mass of the Jelco HS-25 headshell is 12 g, totals 20.5g. This results, due to several diagrams, in a eff. mass of the arm between 20 and 27 g (w/o headshell), presumed the compliance of the 103R is between 8.5 and 10 um/mN at 10 Hz.
I think the eff. mass of the 750L is rather high and it will be difficult to find other suitable cartridges for this arm, I think only the Denon 103/103R and Ortofon SPUs will suit. My Benz Micro Glider with a compliance of 14 um/mN already has a too high compliance for this arm.
Anyone any idea wich other carts would suit this arm?
