Which one do you think is correct?
I think the second is.

Core pulsing at the resonant frequency of the chokes [each is a parallell LC tank], maximum voltage will develop with positive at the dot, while having an infinite impedance.

The dots are the positive EMF according to Lenz law.

See WO89/12704

Both choke coils are wound together.

The polarity is DOT positive.  That is where you start winding the coil.  If it were dot negative he would be sending the pulses in the other end.

If you dig up the above mentioned Wo, and look at figure 9 you will see that ALL the coils are wound in the same direction.
Note the connections made to the chokes from the secondary in each picture.

The DIFFERENCE between the two Pics is the direction that he wound the coils.
In fig 9 he winds the coils counter clockwise from the Dots. in 3-23 he winds them clockwise, but because he wound them in that direction he can rotate the choke coils and dosen't have to route the secondary wires across the bobbin cavity.

The confusion of it, is for convienence of winding it.

All you have to remember is to wind them bifilar together, and connect them with magnetic fields aiding.

crap, I placed the dots as an indicator for positive EMF incorrect, based on Lenz law.
[dot = positive emf]
