The first thing I always do is install a new power cord with a polarized plug and an inline fuse. I agree with moving the line capacitor to the other side of the on-off switch, along with the fuse. I also like to take the additional measure and replace the filter cap/caps with safety capacitors.
The 38-10 & 40-150 I recently worked on had the bakelite block with two .01uf caps on the input power, so I replaced them with Y2 safety capacitors. This ensures that there are no issues as could be the case with a non-polarized plug and its orientation. Even though AC sets have transformers, it doesn't hurt to put in an added margen of safety. I think if you look around and read other articles about this very issue you will find a polarized plug doesn't hurt and is recommended.
