Hi Pablo,

Congratulations on your Beogram 5005. It's a great looking unit.

I think you may need an RIAA amplifier between your Beogram 5005 and your amplifier.
Beogram 5005 does not have a RIAA built in. This includes my own.

No RIAA.

Jesperb, Martin, thank you for your reply.

I got a friend's receiver with phono input to test my unit.

Here you can see that his system works well:

But when I try with my 5005 and the same vinyl, the sound is quieter and very noisy. Do I need a new cartridge? or could it be something else?

Thank you

Hi Pablo,

Make sure the tracking force is set to at least 1.2 grams. It kind of sounds like the MMC4 is not seating into the record groove. I have had that happen once in a while. Try some different records (after setting the tracking force). If it is in the groove and sounds like that then the cartridge is faulty. The cartridges can be rebuilt though.

Hi Sonavor, thank you for the suggestions.

I set the force properly and tried different records, so yes, it might be the cartridge. I did not use an external force measuring sensor, I just place the lever in the right mark. I guess that's calibrated and its trustable. However, given that I do not know the previous history of the Beogram, maybe I should consider using an external sensor to actually measure it?

Yes, please use a separate tracking force measuring device. Something

It looks perfect to me. I can see the tip and on the tip the little tiny piece sticking out. All straight. Let me try to get a picture of it.

Yes, it looks good from the outside. But the MMC4 cartridge is still the most likely cause of the problem if the tracking force setting on the Beogram is calibrated and set.
