Yes, I would feel safe using it because I didn't fool with the fuses in my preamp.

Are you sure about that?...
The fuse in the preamp provides absolutely squat, zero, ground fault protection for the power cord. The fuse is only there to protect the equipment from an overload, short circuit, or a ground fault larger than the load plus the ground fault. And unless the breaker feeding the branch circuit, the power cord would be plugged into, is not a combination AFCI, (Arc Fault Circuit Interrupter), branch circuit breaker your house could burn down in the event of an arc fault.
