I am looking for a complete service manual with wiring diagrams and parts list for the LINN MAJIK-1.
The amplifier belongs to a friend. She accidentally spilt coffee in it. );-):
The effect was that the T3.15A fuse blew. I carefully cleaned the top of the circuit board and almost got all the dirt off. The underside of the main board still looks good. If you measure the resistance at the mains socket when the amplifier is switched off, it is high resistance.
If you switch the amplifier on, you get a short circuit at the mains socket. If you disconnect the 6-pin cable that connects the small mains socket board to the toroidal transformer, the mains socket remains high-impedance even when the amplifier is switched on.
However, the toroidal transformer itself makes a good external impression. It is also well wrapped in plastic film.
If I leave the 6-pin cable connected and disconnect the 3-pin cable that goes from the toroidal transformer to the rectifier on the main board, I also have a short circuit at the mains socket.
Hello!
Disconnect the secondary side of the mains transformer (3-pin connector) from the panel.
The six-pin connector goes to the mains voltage selector, it should be connected.
In this case, a few ohms can be measured on the primary side of the transformer. Do not measure with a short circuit detector, but with an ohmmeter. If the fuse is not damaged either, then the secondary voltage of the transformer can be measured on the 3-pin connector.
In this case, the transformer is good, the fault is in the mains panel.
If liquid spills in, the mains transformer is not usually damaged, but the power supply/output stage is most likely damaged.
