For a Simple AM Radio Circuit (crystal radio w/amplifier) Does the Earth connection only apply to the tank circuit? Answered

So in case the question in the title of this post wasn't clear. I would like to know if, for an am radio circuit, a very simple one consisting of a tank circuit and a amplifier circuit. Does the entire circuit need to be grounded to EARTH or just the "tank" part of it?

There is no difference. They share a common ground so if you ground it to earth then the whole circuit is ground to earth.
