Unfortunately it is not so simple - the 3rd coil is coupled to the
secondary by a piece of wire which in turn may be coupled to the
primary in a number of ways. It is not so much a matter of
"criticizing" the magnifier as it is of quantifying its benefits, if
any, over the 2-coil system. It isn't a matter of faith either. My
views on the subject are a direct result of measurements I've done.
Transformer faceplate ratings simply don't count - I've pushed
a 300W rated transformer to 5x its rating - easily. What does count
is output vs wallplug draw assuming all else is equal. I've seen
quite a few examples of Richard's work and admire what he's done
greatly. My question then is: how does Nemesis stack up against one
of his magnifiers if wallplug draw is the same? One is forced to make
assumptions that all losses not directly associated with the
secondary system are the same.
