Is such a section likely to provide much useful shielding?Well maybe you’re creating a nice shielding effect using the thick steel.
Is good engineering to utilize a single component to accomplish more than one thing.
If it will be oriented to take advantage of that anyways…
I would have thought that the section would have to run the full length of that amp chassis to be a useful shield?
This was my planned orientation, with dummy psu board showing its location.
Is this going to be better? Amp stage added in the back ground for clarity.
