That's essentially what I did, though I tucked mine inside the radio cabinet behind the speaker.

These pictures don't show this addition, but if you look closely enough, there is room for a board behind the speaker. I also moved the power cord cheater cord socket away from the AM ferrite rod antenna. There's a masonite back cover you don't see here as well.

Caps in the filter are X2's.



This mod almost makes it seem like the early 70's on the AM band, before switching power supplies existed.
