Grado F3+ cartridge pairing with Numark 1650? Hum??

Anyone ever used a Grado F3+ or a blue on a Numark 1650? I know grado's are a bit choosey with the shielding hum and certain TT. I got an opportunity to grab a cheap cartridge, but would have to spend on a stylus and if anyone has any negative reactions with the pair, I'd probably shy away from buying. Thanks.

try to rewire it again, the screws on the headshell may be to tight also dont tighten them up to much.

i have agradonever had a problem with it never hums for me.

I'll prob just fork out for the blue stylus and try it out.
