Main Filter with DC Blocker

Many thanks, I’ll read through the Astrodyne documents

I already have an aluminium box fitted with 4 sockets with some room to fit the filter and DC blocker. The box is grounded to the main ground so should not be a problem I think.
Of course a shield power cable from the box to the amp needed.
My amp chassis is a wooden box so it not shield but maybe I would consider changing this at later stage.
