Re: NCX-5 powered by NCX-A keeps blowing fuse
Do not change any component just for the fun of it. Find the fault first.
Diodes chould have one end disconnected to test them although a dead short can be detected without disconnecting.
C1 and C2 are connected in series with R1 to R4 providing balance. Check these resistors without disconnecting.
Work your way from input to output. Repair and test each section separately before moving on. Remember that intercomponent wiring can be faulty.
I have a PSU here which was operating poorly. Someone had changed components and reinstalled the rectifiers to give half wave rectification instead of full wave. Obviously a compulsive changer.
