Hello!

My name is Philipp and i am new to this forum, but not new to the B&O World.

A friend of mine recently gifted me his old Beogram 1600 (along with speakers and amplifier).

Yesterday i realized that the turntable is slightly faster than 33rpm, i would say about 1-1,5 seconds per minute.

Does anyone know if this is normal? Ist there any way to fine adjust the playing speed? Or is it a mechanical issue?

The beogram is in an overall good condition, everything else works fine!

Thanks in advance for any answer!

 

Kindest regards from Germany

Could be an incorrect belt.

I believe these have the pitch adjuster above the rocker switch.

There are free phone apps that can be used for speed adjustment or get a strobe printout from vinylengine.

Thank you very much for your answer again!

“Sadly“ i have the version without the pitcher above the rocker switch. Thats why i thought that maybe there is something like a fine adjustment inside the turntable.

I also thought that the belt might need a replacement...but how do i get inside the device? With my other beogram, i just needed to lift the platter but this one cant be lift somehow...like its stuck or something. Any advices?

kindest regards

Hi!

 

Thank you very much!

 

Sadly i cant find a manual for my beogram? Is there anyone who could probably send my a scanned manual?

Also do you know how to open the beogram?

 

Kindest regards

Hi,

I have never seen this model but I should imagine it’s the same as the normal 1600 in which case

 

There are 2 trim pots inside for the 2 different speeds

 

There are lots of manuals on the site for silver or gold members,

 

The 1600 is not here look for the 1102 a very similar model

 

(if it were mine I would also change the belt)

 

Best regards Alistair

Hello!

Yes, i want to change the belt as well! But how do i get inside the turntable? Just lift the platter or is there anything i need to "unlock"?

I also added some pictures of the turntable.

Ok, i tried but somehow it is stuck...

I am a bit afraid to damage anything to be honest...the platter on my Beogram 4500 lifted quite easily

It just binds to the subplatter - unless someone glued it  (yes, I have seen that!).
Keep lifting, using "controlled force".

The handle on the tonearm is not original.
Does the tonearm movement and lift/lower work as intended?

I can supply the correct belt.

Ok, yea it feels like its glued but since i know the pre-owner i highly doubt this...any advice on „controlled force“?  :D

Good observation skills! I built the handle myself using a very thin and light piece of metal, just so it ist easier to lift the tonearm while the record is playing. It weighs exactly 0.242g so i adjusted the weight on the tonearm. Works pretty good. Tonearm works perfectly as well.

 

I will send you a message regarding the tonearm!

 

Thank you all for your help!

So after working that thing i finally got it off! It was indeed somehow stuck/glued together with i don't know what...

I checked the service manual from the Beogram 1102, so i think the adjustment should be like this? (seen in the image attached)

Fine adjustments
