Having seen photos of the CURSE primary, I am interested to know which is the
better primary topology -the grounded-centre or the grounded-outer?

I myself use a grounded-centre design and tap outwards to add more turns, but
from what I have seen of the Danish coil photographs it appears that the
primary is connected at a point someway between the centre and the outer
primary turns to the base of the secondary through a number of small black
wires- are these grounded or not- also if the black wires are grounded where is
the "hot" end of the primary -at the inner or the outer turn?
