A 60hz low pass (LC) filter will help a lot but is not as easily slapped together. A compromise can be made by putting a set of .047 to .1uf 300v non-polarized caps across the power line and to earth ground (very solid earth ground). >-----------------------------------------------> | ----- ----- | --------- | | ----- /// ----- | >------------------------------------------------->
