Unfortunately the signal of the left output comes and goes. So I opened the box up and saw that a wire that are soldered to the right output and that goes to the left are almost completely off and it needs to be repaired.
I’ve found these wires that are for repair work and they are designed for max 60 V and 4,3 A.
Is that the right wires to use?
Is it safe to do this myself? I’ve soldered once before and it went ok. Do I need to measure anything with a multimeter before turning it on after the repair?
In my mind, it’s a simple repair, but it’s best to ask before to avoid any mistake.
Probably don’t need to replace the wire, check the continuity between the PCB connector and the output connection, might just be a loose crimp inside the header, or oxidation.
The mains wiring is pretty dangerous - I’d be quite cautious with that build… (eg if that wire you circled detached and touched the, what looks like, exposed mains terminals or switch you could very easily have a live case). Also, depending on where you live, it looks very much like the colours for the mains wiring are incorrect which is dangerous because it increases the risk of confusion when working on it!
I’d be very very cautious if you dont know what you are doing !
Yeah, but I am unsure if the wire is long enough for that. I will check that. The wire are soldered on the right output and then goes to the left output and soldered together with the wire that goes to a connection on the PCB. So it must only be an audio connection. It’s a balanced connection, so and its 3 wires = Tip, ring, sleeve. I would never start messing with the PSU mains.
But if I need to replace the wire with a new. Is the type of wire that I mentioned the right choice?
Its wires that are for repair work and they are designed for max 60 V and 4,3 A.
Well you could strip the wire and extend it with a piece of the same type (probably 16/02 or 7/02? The first number is amount of strands, the second the diameter of each strand - 0.2mm) and use heatshrink or insulation tape to cover the join.
Bad solder joints are bad connections. Not the end of the world, but while you’re in there soldering, may as well hit them all so you don’t have the same issue in the future.
