Hello fellow Beoworlders,

Thanks once again for your regular support.

I have a question regarding the tone arm height of the Beogram 5005.

I apologise is this question has been asked before, but I have not found a definitive answer to my problem.

The problem that I am having is that when I am playing the newer 180 Gram vinyl records, the stylus is uncomfortably close to the surface of the record.  I have in fact heard the needle make contact with the record once while returning to the rest position when it has finished playing. 😉

Another problem I am facing is that on many records (not just 180 Gram) on the last track, there is a scrubbing/scraping noise as the record rotates, sounds like the record is catching on the top left corner of the plater/deck.  It is my understanding that there are setscrews under the platter to adjust the suspension (correct me if I'm wrong), but by raising the spatter from the deck, would this then make the other problem by bringing the record closer to the stylus?

My uneducated guess would say that there's an adjustment screw to set the height of the tone arm?

The tone arm currently rests horizontally, and is parallel with the indicator arm when it is in it's raised rest position.

 

Many thanks in advance.

When I get it right, there are 2 problems with your deck. Lifting the platter by adjusting the suspension will also lift the tone arm. This will only cure the scratching. But you can try to lift only the upper platter by putting kind of spacers upon the sub platter (3 resting points)

Perhaps I got you wrong when I posted my first answer. The heavier records are only a little higher. Yes, there are several points that can be adjusted. When you say the tone arm is horizontally, do you mean, that it's parallel to the record in lifted position?

You need to check and adjust two things.

First check that the chrome rails are correctly pressed into their holders and the sliding carriage is correctly mounted upon them.

Second check that the platter height is set correctly so that the top surface of the platter is 2 mm above the surround.

Just to add regarding the platter scraping, 180 g records are by definition around 30% heavier than regular records (which I believe are pressed on 120-140 g vinyl). So even a correctly adjusted platter/carriage will sink deeper when playing them, and you might need to compensate a little, especially if the springs are tired. This of course will not affect the distance between the arm and the platter as they move together.

Thankyou for your help and suggestions regarding my problems.

I am away from home at the moment, so cannot check on the various things that you have suggested.

It now seems obvious that raising the platter will also raise the tonearm, due to the unique suspension design of the beogram, a simple relationship that I had overlooked at the time.

I will check the various points that you have mentioned as soon as I get back and report my findings.

I should also mention that the scraping/scuffing sound is not only occurring on 180g records, but also older 120/140g records.
