Hi, I'm new here, I hope posted the thread in right section.
I have on my workbench a linn switching power supply of a CD player Linn Karik.
The supply has no voltage at the output, it's dead.
Can anyone help me with a schematic? Thanks.
I found an irf740 fault, replaced, but doesn't work.
Thanks all for the helps.

Usually what dies are the unobtanium control IC's, but can be a simple fuse or bad caps at the outputs.
Thanks MAAC0, the schematic is impossible to found?
I can thought to replace the ps, but I don't know the voltage.

Welcome 27!
I've seen a couple of threads around that the caps are sometimes suspect on these. Such as:
Linn Brilliant SMPS - naked! | pink fish media
I've heard of people having luck swapping out the fets and caps and bringing the PSU back to life. YMMV of course.

Replace the caps is not a problem, but for replace transistor or diode without a schematic or component list it's very hard. What type of fet I have to buy?
