First, you may wanna check with some dealers who might still have Grace replacement stylii (F9E, L & Ruby will work with that body)in NOS stock. Try Lyric and Stereo Exchange in NYC & Needle Doctor.
Also, the 707 is a very low mass arm, so best not to use low compliance carts, such as Denon & some Grados, with it. Shure V15 series will work well, as will most Sumiko Blue Points & Ortofons.
Caution about low output MCs, many will not have enough gain to stay out of the too-much-noise range w/your preamp unless you also get a head amp or transformer.
Best of luck,
Joe
