BS9000 MK I – power PCB schematic

[kordina]

Hi guys,

I have a problem with my MK 1 and unfortunately the site service manual is not complete. Does anyone of you have the schematic relating to the power board? It´s the circuitry relating to the voltage generation around the LM3578 (there are at least 4). Unfortunately the MK2 and 3 are completely different thus I cannot use those manuals as help.

Regards,

Staffan,

Apologies for the late reply.

As the BeoSound 9000 Mark 1 manual is about 2 cm thick I just scanned the power supply section which is below and attached in a PDF. Click on the image to see it in large format.

Excellent Keith! This is the schematic I need!  Would it be possible to copy the related PCB to allow me identifying the components on the board?

Many thanks in advance!

Hi,

If I wasn´t clear enough, the service manual also show the layout of the boards. I would need a copy of the Power Board layout to clearly identify the components in the schematic 🙂

Luckily I have a working Beosystem 6000 which is doing it´s service of entertaining us 🙂

Sorry my mistake Keith. I checked my data again and found the PCB layout I needed.
