Owner manual specs: 500VA Max power consumption.
500VA / 110V = 4.55A. The designer of the amp only bumped the fuse up 110%.
4.55A X 110% = 5A. A 5A slow blow fuse seems a little tight to me for the amplifier...
500VA / 230V = 2.18A X 110% = 2.4A (Round up to 2.5A.)
(500VA / 120V = 4.17A X 120% = 5A)
