I thought perhaps I screwed up my coarse attenuator stopper positions.
Then I noticed an older related thread from the first Mainline run and it would appear I don't have the 0db marker as stated there. Or now reviewing the manual - as pictured there.
My coarse attenuator has 6 positions. The first position is -45db... through '0db'. I'm fine with this configuration, but just looking for confirmation I followed the build correctly.
I don't require a replacement plate. I think it would be a bitch to tear apart.
