Which fuse should we use with a 400w amplifier.? It uses a step-down transformer with 27-0-27 10A, 12-0-12 1A and 18-0-18 1A secondary AC main is 230V. Fuse need to be placed before transformer. So power switch, transformer and fuse will be in series.

400W / 230V is 1.73A. So a 2A fuse should do the trick as long as startup inrush current isn't large.

Thank you. My power supply uses 14700uf electrolytic caps on each rail of 27.0.27 supply, (( 10000+ 4700)*2), 4700uf each on 18-0-18 1A part and another 4700uf on 12V 1a part. How will be the inrush current?
