Hi Jeremy David Colin and other commentators.
Ok I may have got the name wrong..not important...
What i needed and have got is the answer to my question....Thanks Jeremy ...... it is not intended to be anything except a Local FM station block. Jeremy I have some nice copper braid, of which I made the lid to case connectors, from some RG whatever coax.... I was looking at a similar thought yesterday which I will now implement.
I will use some 1 nf Feed through caps for the DC and Audio out, as I have a fair few.
I will report back when I have tested it, with and without a lid seal..but thanks guys..
