Question
QUESTION: Hi,

I have a turntable that produces sound without being connected to speakers. From what I can hear, the sound resonates all across the plastic base under the vinyl record, so I guess the source of the sound is somewhere there, i.e. embedded in the plastic base, which is also completely sealed off. Any ways I can get rid of the sound turning on by itself or lower it?

ANSWER: I don't understand what you are talking about.
Please clarify to me:

Make and model number.
What does the it sound like?  Hum, sizzle, rumbling, static?
Does it go away when you turn the set off?  Unplug it?
Does the sound come out the speakers? or just inside the TT?

If it is a hum, does it come from the power transformer mounted
inside the unit base?  Try to identify where it is coming from.

Then, answer my questions so I can help you determine the right
path to follow.

QUESTION: Well its an actual record sound. It's of particular volume. It's always the same. I still don't know where it's coming from. And it's pretty loud so I can't control it you see.

The main generator alone hums really loud on its own but when I switch it to the radio mode headphones work perfectly and no sound is produced externally. When I switch the mode to phono, i.e. turntable, that's where the sound is being produced externally. The wires inside the box and everything else is fitted 'just' to work.

The make is 'Murphy' if you have heard of that. It was the cheapest I could get in 2006 around 30 pounds sterling or around 50 dollars. Here's a link with picture of exactly the same build only under a different label:

Sorry cannot photograph the real thing as havent got the camera.

My problem is that I'm not that good with physics i.e. I can't get my head around whether it's just that mighty generator or another bulky motor or something atached to the base of the turntable or it's coming from within the turntable base which is plastic and sealed, and I guess to look inside I need to break it. Basically a very cheap model.

Answer
Sorry, I don't understand.   

What is a "record sound"?
What is the "main generator"?

You did not answer my questions so I cannot help you.  Without knowing the nature of the sound and where it is coming from I cannot help you.

Maybe this will help you with your own troubleshooting:

ONE:  Play a disc and put your ears close all around the unit until you know where the speakers are located so you can listen very close with your ear right up against the speaker.

TWO:  Turn the volume down to zero or minimum and put your ear close to the speaker.  Is there some sound coming out of the speaker?  If not, try to determine where it is coming from.

IF:  The sound is coming out of the speaker, is it a hum, a sizzle a chirp?  If it is a hum it means the power supply is defective and needs service.

IF:  The sound is coming from inside the unit but not out of the speaker it means either the turntable is making some noise when it rotates or the power transformer is loose and causing a hum or vibration sound against the internal chassis.

Do not try to get inside as you may cause damage to the unit.  

I suggest you will probably end up taking it a shop for diagnosis and repair.  It may cost more than you are willing to pay however, sorry to say.

Wishing you the best,
