I have a Technics turntable Model: SL-BD22-KM, Ser.#: GF3Fc73813. The RCA and ground connection panel on the turntable has been jurked-out tearing the wires apart. I need to know which wires are soldered to left and right channel RCAs, the black ground wire is okay. The wire colors red, green, blue, and white and as you know there are two wires each RCA plug, one in the center and one outer edge of the RCA plug. Can you advise?......Thanks, Pete

A grounding wire is just a piece of wire connected to an earth point on the deck, connecting to an earth point say on a radiator pipe. There's nothing special about this wire any old piece will do. You only need it if you get a hum noise when the turntable is connected to the amp.

Usually, on Technics turntables, the ground wire is attached to a ground lug on the receiver.

If you need further help, I’m available over the phone at https://www.6ya.com/expert/david_29ad5d1dd86564b0

YOU PROABLY NEED A PHONO PRE-AMP IF YOUR RECEIVER ISNT ANCIENT.

Earth cable available here :-

just get any small speaker wire and use that as your ground , attach that to the reciever you are using

Yes you need a pre amp

It would also be the same if you connected it to a computer to record an LP to CD. Mine is a little different and has one already built in that I can switch in and out of line.

Try spend a little more if you can as many pre amps can introduce noise.

You may also want to check that the turntable is properly grounded to prevent noise too

go to RADIO SHACK and get a pre amplifier module (hope its still available) , that will do the trick , AJ

If everything seems ok with the power , there is usally a small microswitch that sends power to the motor when the tone arm is moved to the start of the record.
The switch might be bad or the lever that actuates it (connected to the tone arm) might be sticking. You may have to take the bottom cover off or remove the platter to see it.
Also make sure the belt is looped over the motor shaft. If the motor runs but the belt still doesnt turn, belt might be bad.

presuming it has "some" effect, then gnd wire itself it good. Even though there may be a gnd thumbscrew on the preamp try slipping the ground wire under a screw on the main amp or receiver that screws into metal and make sure the gnd wire is touching metal under the screw.

if that didn't help, then you may have:
>a cartridge with an open gnd internally.
>an open gnd wire from the back of the cartridge to the outer shields of the RCA connectors.
>or your neutral & hot wires of your house wiring might be reversed causing something weird.
>a low quality preamp. (it should have a seperate wall adaptor so that only low voltage dc goes near the preamp)
good luck ground issues can be tough!
