UPDATE: I figured it out, its 4-6 grams, and I figured out that 2 dimes installed aboved the cartridge between the cartridge mount and the cartridge itself is the right amount of weight to get the tonearm to track correctly, the nice thing about this cartridge is that its able to play stereo records no problem (its got a 0.7 mil LP needle.)
I ended up having to use the FM audio hookup on the back because the more modern ceramic cartridge isn't hot enough to be able to use the original Phono hookup.
