Well Beoworld community, with your help now everything seems fine and I like the sound of this turntable (along  with the beomaster 5500 and beovox s60 speakers). Later I'll check all the arm setups. Now I have a problem: there is a bump when the disc ends and the arm rises. How do I get rid of this "bump"?

Thanx

Loris

That fault is probably in the muting / silent circuit - I have it as well, but haven't bothered to look into it yet.

In 4002/4004 the muting is done with a relay, but in BG6000 it's electronic and integrated into the CD-4 decoder. I seem to remember Menahem found a faulty diode in his BG6000 that caused this?

I have another problem🙁 the left channel is lower than the right one. I have an image between the center of the speakers and the right one. I swapped the speakers and changed the input from aux to tape 1 and it's the same. The 5005 I have doesn't give this image and also the cd player doesn't.

???

Thanx

Loris

The muting relay is always suspect and is the obvious place to look.

But there are some not so obvious places to look as well:

1) Is cartridge functioning properly?
2) Any dirty contacts on the cartridge connector on edge connector?
3) Check solder connections on shielded cable INSIDE the DIN shell. Also check other end of shielded connector for cracked solder joints/frayed wires.

I have found cracked joints many times before inside the DIN shells.

I'll start to check 🙂

The diode was a Germanium AA143, crosses to NTE110A.

I have one AA143 left, if by chance, it is the same diode.

But remember, a Germanium diode has a normal Vf of about 0.25V, whereas if you saw that value on a silicon rectifier, it would be faulty.

I thought  I had  fixed the problem. I remade solder connections inside din cable and cleaned the 5 pins.But the image is still on the right.

ps Manahem, thanx for your offer. Will it be an easy task? I don't even know where is it...🙁

Hi, R U all in vacation? 🙂 What should I do now?

Loris

Well....

Take the cartridge off of the tone arm.

Press play and wait till the tone are releases and the mute relay engaged. Then use the continuity function of your multi meter and check for continuity/resistance from the din shell to the fingers on the tone arm.

If all is well then most likely you have a bad cartridge.

You may also try to swap L+R wires inside the din shell. If the lower output channel moves from one to the other then it is likely also the cartridge.  If not then perhaps its your amp!

It's all deduction at this point.

this is true if there isn't a phono stage inside the 6000, but it's there. if this board has some bad component...... this could be the problem
