I'm the owner of a Philips B5X42A that I've just opened and started to renovate. To my surprise I found a capacitor connected to two lugs (lug 3 and 4) near the back of the radio that was shorted by purpose with a wire. When I then checked to schematics it also showed the same thing.The capacitor is C107 in the schematic (10nF). The short circuit over this capacitor also makes a short circuit over R101 (10kOhm) and C100 (80uF). Can anyone, with more knowledge, please explain the purpose of this circuit? It sure puzzles me.

Hello Mr. Oscarsson,

this will be a connector for a stereo decoder.
Please make a photo of the contacts.

If a stereodecoder is used, the short circuit must be removed at C107.
And the connections for contacts C19 / C12 must be connected separately.
Look at the stereo decoder at the model B6X44A, This decoder is similar.

Regards WB.
