Beomaster 8000 strange parts on Board No 7

[spassmaker]

Hi dear members

I’ve a question about an BM 8000 eich I’m working on.

During inspection of Board No. 7 (Relay Board on the back of unit)

I found an capacitor C2 4000uf and two diodes D3 /D4 MR501 on that board which are not mentioned in the service manual. Have tried differen manuals but no success to find.

These diodes are not the flyback diodes of the relays.

Maybe someone could give information about these parts.

Attches 3 pics from the board.

I think that it may be a network to reduce hum from the torroidal mains transformer in stand-by.
