Hello I can't find the schematics  for this Beolab 1-  6841 model.

I only find the service manual without schema .

Even specialized websites like Elektrotanya, or other  do not provide the schematics, we just find documents on the disassembly or the adjustments of the Beolab 1 and I searched a lot !

Can someone provide me with these schematics  or give me a link to find it

Best regards 

Stephane

What you are looking for was never disclosed to the public.
Only very few people sit with this information and they can't/won't share it.

Is there a special reason for that?

I mean most of Beolabs have their SM whith schematics and everything, I think? Why not the Beolab 1?

I think it has never been the case for high end models, like BL1, then BL5...

Yes, I don't understand why there are restrictions for this model.

I tried to make comparisons with the Beolab 8000 (diagrams available) which also uses an STK 4231V, but the comparison stops there, because the rest is different on the Beolab 1

I saw that there are MOSFET transistors (D40NF03) just before the output inductance towards the speakers. It is not conventional as a scheme!

The symptoms are a bad distorted sound and quite weak on the woofers especially ( speakers are checked and OK)

I don't know why.
Rights, perhaps.
