I would probably build it P2P... no need for a pcb with such simple setup.

Joachim, why only a 100mH choke? I like these as an alternative to the prohibitively expensive Lundahls better.... Frag Jan zuerst- Ask Jan first: Roehren und mehr, the 10H 330R choke

hello Stev,
one one hand,
you're absolute right.
On the other,
does a perfboard match with those red cuties ?

Actually better than I expected, even without any modelling of common-mode

Actually the original design had the Talemas BEFORE the diode bridges to get rid of the HF/RF noise from the transformer. They can be used though in a conventional CLC pi filter like you did simulate. A bigger inductance is even better, sure, but they are inexpensive so good for experimenting with this technology.
