Totally struggling with how to get a start on this!
I'm in the UK (240v) and transformers (toroidal) are 300VA 50-0-50's (in a pair of monoblocks that I'm restoring)
Presently...the only protection is a 3A fuse at the wall plug!
Want to protect both primary/2ndary...and tbh...haven't a clue how to go about deciding on appropriate value of fuses
I have A-level Physics, (dim and distant past I'm afraid) and can recall my P=IV, and V/I=R...etc...but don't know where to start here.
Have attached PSU circuit diagrams, and hope that someone out there might 'walk me through' the process of calculating fuse values!!??
Perhaps there's some kind of fuse 'calculator' out there that could help??
Many Thanks
