Kim,

Is the amplifier a 120 volt or 240 volt edition?

If it's a 240 volt, you might consider upgrading the power cord to 
a four-conductor, Hot-Hot-Neutral-Ground, so as to provide
a separated Neutral where no a.c. return goes on the chassis
ground lead. It's a recent upgrade to better safety with
240 volt appliances that incorporate return conductors 
from either of the 240 volt legs to a common.

Secondly, with either a 120 volt or 240 volt cord you
might consider upgrading to type SO, or SOW, or SOOW 
cord. These are rated for wet locations and have 600 volt
insulation characteristics. You would more than likely
need to procure a flexible cord connector for the chassis
that's rated at the cord diameter, (e.g.,  10-3, 10-4 SO, etc.),
but it sure makes a beautiful, sturdy and long-lasting
addition to your appliance.

The cord is standard 3-wire rubber-jacketed cord. 
To my surprise, there was no flexible insulation left anywhere.
