There is an AGC 2 fuse installed which I do no believe is OEM. Fuse is blown. Question: based on 65W of power consumption at 115V is this the correct size fuse?

As always, any help is appreciated.

P=IV so 65W/115V= 0.56 amps steady state. 2 amps is better than nothing (the radio was not originally equipped with a fuse) but a better choice would be 1 amp slow blow.
