There is a basic PCB seems the only difference is someone has added the power cable to the “f1” not sure why , now is exactly the same board apart from the power wires that someone soldered on! Mine has a 3a 125v lf459 fuse where the “f1” is on the board.
I have tested the psu and it gets 24v power. I gets 24v power when tested the 3 big lumps of solder that are on the psb. It looses power passed the 3a 125v fuse that the place marked “F1” so I tested the fuse doing a continuity test and it failed so I guess that has blown, I have ordered Micro Pico Fuse Time Delay / Slow Blow Axial 3A 125v to replace that.Should I just replace the fuse and see what happened?
