[Boatanchors] line cord question

[Michael Bittner]

Where should you put line noise suppression capacitors in this setup and 
what value should they be?  I'm thinking .01 uF, 600 V, one from each side 
of the power transformer primary to chassis ground?  Or should they be 
directly across the line input? Before or after the fuse or power switch?
