THE DDT - II SPECIAL A custom handbuilt moving coil cartridge with VDH-type 1 tip, boron cantilever, matched crystal silver-wire coils and 0.65 mV/channel. The designation “Special” in this cartridge’s name indicates important improvements over its previous version: The cartridge is equipped with a thicker frontpole and an extra small magnet, both further enhancing its resolution capabilities and output voltage. The cartridge’s name DDT stands for Depth, Detail and Timbre. stylus shape VDH - I stylus radii 3 x 85 Micron frequency range 5 - 50.000 Hz tracking force 13.5 - 15.0 mN static compliance 28 Micron/mN tracking ability 70 - 80 Micron output voltage 0.65 mV RMS channel unbalance < 0.75 dB channel separation > 35 / > 30 dB stylus tip mass 0.35 Milligram system weight 8.2 Gram vertical tracking angle 22 Degrees load capacitance see (*2) load impedance 200 Ohm eff tone arm mass 8 - 12 Gram moving coil resistance 9 Ohm +/- 10%
