Technics SL-BD20D Turntable - Answered Questions & Fixed issues


Different cartridges put out various levels based upon their technology - make sure you are using the proper input for their output. A line level input 1V P-P won't work on most phono cartridges and will require a preamp to boost it to the higher level.

Take off the rubber mat and see if the belt is off the aluminum platter the record sits on you should be able to see the rubber belt when the mat is removed. If it is not there or broke it will need replaced.

The ground cable is usually a part of the audio cable. A red lead(right channel) and white lead(left channel) and a black lead. If there is no black lead, you can connect any wire to the metal portion of the turntable and the ground lead on your receiver. For more information, or should you have further question, please visit my website at audioserviceclinic.com. You may contact me through the website. Thank you.

There is really nothing else to it. If the drive belt is in tact, and properly installed, and the spindle motor is rotating properly, your turntable should rotate. There's nothing else that rotates the platter. Just make sure the belt is wrapped around the spindle motor.

I just checked my Technics turntable to be sure and there should be a thin black wire that comes out of the rear where the AC line cord connects. If you don't see a wire, someone may have clipped it off. You may have to disassemble you turntable enough to get access underneath and install a new wire.

Too causes of this problem. One the stylus is worn out. Two not enough pressure to the stylus. At the end of the arm is a weight this should move up or down. If you can see numbers on it increase it slowly to the higher numbers, trying it as you go. The trick is to apply the correct weight to keep the stylus in the grooves and not here a rumbling sound from too much pressure.

Hello,
You don't need the original ground wire for Technics SL-BD20D turntable,
any plain cable can be used for this purpose...
you should connect turntable to your pre amp,should be a "phone" input at the back...
here are some suggestions for grounding....
---------
  • Plug in a surge protector to the outlet, and then plug all the components into that surge protector
  • Connect a ground plug to the surge protector and then plug the ground plug into the main outlet. A ground plug is available at any hardware store, and turns a three prong connection into a two prong. Ground plugs help eliminate 60 cycle hum.
  • Connect the ground wire from your turntable to the ground wire connection on the receiver. If this doesn't work, looking on the back there should be a grounding point,

    Unplug your receiver.. Split a wire and attach one of the splits to the receiver where you will see the text, "ground" or something similar. Attach the other end to something metal such as a pipe that goes into the ground. Secure with electrical tape. Plug in.
    connect the ground wire to a screw on the electrical outlet.

    Poor ground at the phono cartridge. Turn your receiver off and remove/reseat the cartridge and/or the tiny leads to it.

    You definitely want to make sure that your new cartridge is properly aligned for your turntable. This web site can help:

    If you don't feel that you are able to get it properly aligned by yourself, a local dealer should be able to help you with this for a small fee.

    I have also had this problem with the same model turntable. I opened mine up and the problem seems to have been that the grease on the arm lift and cueing lever was gumming up the linkage between the two. (I suspect that my turntable hadn't been used in some time.) I managed to free up the parts by manually working the the arm lift (pressing it down) several times. I'm not sure that I needed to open up the chasis for this fix but it did help me to see what was going on. Good luck with yours.

    Are you sure it's not the amp it's connected to that's not the problem? Magnetic cartridges have to be amplified by a pre-amp inside the main amp. It's sole purposes is to do just that, so the rest of the amp can work just fine. Most of these pre-amps are just a single IC and a few other parts. From what you describe the IC is perhaps getting hot, due to some internal fault, when a signal is applied to it. Break the signal and it cools down making it sound normal. There could be one in the turntable itself, but I doubt it.
    If you are good with a soldering iron you will find the IC by tracing the wires back from the turntable imput socket on the amp. Conecting the turntable to another amp will confirm it either way.
