Another solution to the need for magnetic shielding covers is to buy some
self adhesive shielding called mu metal.   It is NOT cheap, but effective.

Made by companies like Perfection Mica Co. for years for CRT shielding and
other critical uses.

A machine shop should be able to copy your aluminum covers and bend you side
panels at least from steel and punch/ drill them for you.

However, it seems easier to set up my shack with power supplies either under
the desk or on a side shelf remoting them from the susceptible radios!
