Van Den Hul The FROG cartridge

Van Den Hul The FROG cartridge.

Made by hand. Needle shape VDH - IS. Coil from GRASSHOPPER III. Frontpole magnet and suspension from GRASSHOPPER IV. This is probably the best cartridge in this price range.

Van Den Hul The FROG comes in 3 versions:
a) Standard - output 0.65 mV / per coil channel of copper conductors covered with a dense layer of silver and a modified magnet.
b) Gold - output 0.65 mV / per coil channel of copper conductors covered with a dense layer of gold and an extra modified magnet.
c) High Ouput - 2.25 mV output / per coil channel made of copper conductors coated with a dense layer of silver and an extra modified magnet.
