Hi there

Have you tested to see if the problem is with the actual turn table or the amplifier? This could be the problem.

The problem could also be because a turn table is analog and not digital as most music players are. Analog will always have that sound, this is caused by the friction between the vinyl and the stylus (also known as a needle).

    Also, the turn table must be earthed or it will also make that static sound.

The buzzing is coming from the cartridge because of a bad ground. Check the head shell for a broken connection. With the headshell removed, you should be able to touch each of hte 4 pins. Two of them should produce a hum/buzz when touched. If the "active" one is shorted to the ground one, there should be no sound at all. If the connections look good, try a new cartridge and needle combination. Unless there is a broken ground wire inside the turntable or the cable from the turntable to the mixer, the only remaining part is the cartridge. This particular unit does not have any active electronics inside, so no capacitor problem can cause this symptom.

Keep us posted on your progress.

Hi,

Pls verify that it is the turntable that produces the buzzing sound and not the preamplifier/amplifier or the mixer (if you are using one). This could be verified by switching the left/right RCA plugs as to how they are currently connected. Should problem persist on the right channel, then it is not the turntable.

if on the other hand the buzzing sound moved from the right towards the left, pls try:
1. check the grounding of the turntable, not the shield of the wires but the body/chassis ground;
2. check the balance/level of the cartridge, it may be inclined in such a way as that there is more pressure on one side;
3. check the connector pins of the tine arm where the cartridge slides into;
4. check for any "bleeding" of the connector pins using an ohmmeter set to high resistance range. Must be no reading at all from any of the wires.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

    Hi again,



    Appreciate the postback and additional information. Have you tried
    running the turntable without the cartridge/needle? If the buzzing is
    still there, try removing then the new wires that you have installed.
    Since it is a process of elimination, the point where the buzzing
    disappears would be the point of further diagnosis then.



    It it were a hum, the it is possibly spillage of the AC power supply,
    but since it is a buzz, then it is relatively high frequency.

    Cheers.

Sounds like a failing capacitor on the right audio circuitry...

    Also try replacing the feedback 33uF cap around the op-amp with a lower value..This can be done at any electronics repair shop. I suggest you take in in to a repair shop for general fault finding on the board.. Could be any number of other capacitors that may be causing this issue as well.

The platers arn't hard and heavy any more


Have you tried swapping out the platters? Sometimes this will fix the problem. Also, although VERY RARE, make sure you were sold the right platters with your turntables. I doubt they found a pair of copy cat platters, but ya never know!

You can remove them by just lifting them up and off. There is a magnet that holds them down, so if you encounter resistance, just tap the center shaft with a wood block, mallet, or similar. Don't hit it too hard, you just want to disrupt the magnetic force, and/or loosen the platter from the shaft (which sometimes gets stuck).

Other than that, I've never heard of this type of issue, and I repair these things for a living.

Good luck!
