Thank you, Steve

I would not use one fuse to protect the radio and phono; I would either fuse the radio only, or fuse the radio and add a separate fuse for the phono if I wanted to protect everything with fuses. A 2 amp fuse will allow double the current to flow to the radio; if the phono is not on and something goes wrong inside the radio, the fuse may not blow until the power transformer cooks.

As Gary pointed out, installing a bigger fuse is dangerous.
