Beolab 3 Power Supply Schematic

[Tommaso Vercesi]

Hello Beoworld, I’m working to fix one of my Beolab 3.

Power supply is gone, problem is likely in the area in the picture, where you can see few components are burned.

Of course fuse is blown now.
Rectifier and few capacitors replaced, but were likely ok.

• Do anyone have a schematic for this power supply (A6143262 Ver G) ?
• Or, do you know what are the components ?

Thanks for help.

Hello

The servicemanual for Beolab 3 only have block diagrams showing the connections between the boards, no component level schematics.

Your best bet might be to compare to the components in a working one, provided you have 2 Beolab 3 speakers
