Turntables require a special input in the amp (usually marked PHONO) because they require high gain and different equalization - and yes, that ground wire has to go to ground unless you want to get a super annoying 60Hz hum from it!
If your amp doesn't have a phono input, you're going to have to go out and get a phono pre-amp and connect it between the turntable and the amp.
Best of luck!

Try connecting the turntable to one of the other inputs like CD / tuner etc and see if the buzzing disappears. if so then your turntable has a built-in pre-amp so it can be connected to any input except 'phono' as this would obviously be used for turntables without a pre-amp.
a lot of modern turntables now have built-in pre-amps to compensate for certain amps and receivers made without a phono input and can now be connected just like a CD player, tuner etc.

hope this helps.

You need a magnetic cartridge preamp. You then plug your turntable into it and the box into the CD/aux imput of your amp.

Maybe too close to the speakers causing "feedback". Otherwise
need more info on the noise!

Turn Up The Master Level

A metal tone arm has a ground wire that connects it to the back of the stereo via the Turntable chassis. If this wire is broken (inside the deck of the turntable) or the ground to the stereo is not done, you can have this issue. No, the ground through the audio connectors is not sufficient.

that turntable wasnt made in the usa . your best bet is to google the same info.
ask where to buy that transformer etc. good luck

The unit should not be making any sounds like that. It sounds like the timing is off for the gearing underneath the platter. It may be as simple as cleaning the existing grease on the mechanism and re-lubing. The existing grease may have gummed up a bit not allowing the parts to move freely. Take of the bottom and look at the condition of the grease.
