John,
I stand my "ground" here. "Ground" IS INDEED "earth", one is the USA term,
one is used in the UK and elsewhere most often. However, in antique
radios we should use the term "CHASSIS" if that is what you are tying onto,
or "B-", also called "Common Negative, or Common neg" when you are tying to
that.

Mark, it is worth noting that some modern high tech IC based equipment
is built on multilayer PC boards, and one of the layers is commonly
referred to as the "ground plane", and even in lesser equipment using
simple two sided boards, there are often large areas of foil referred to
as a "ground plane".

I think your condemnation of the term "ground" is misplaced given its
common usage even in the most modern technologically advanced equipment.
I think the problem is that you are confusing "ground" with "earth" and
they are not always the same thing.

john Byrns

""to common B-" is fine if thats what you are tying to on a return side,
but
"to chassis" is the correct term in the case we were dealing with here.

I just want to break the habit many servicers have of saying "to GROUND"
as
its definitely NOT "GROUND" unless you bond the chassis to ground...and,
90%
of the time its just not... and a goodly portion of the sets being
restored
are indeed what can be called "hot chassis" or AC-DC sets... which,
unless
converted to have a polarized plug with ground can not be referred to
ever
as being grounded.
