[...]The mod calls for a transformer primary winding using 12 strands of 0.3mm e.c.w. (enamel covered wire). I assume that the 12 strands are used to improve the Q similar to the way Litz wire works? 
Yes, confirm.
Has anyone done this mod? Has anyone tried alternatives to the 12 strands of enamel wire?
I don't have that PA. But the 12 strands just improve the efficiency a bit. It would work with 10 or 14 strands as well ;-) These are easier to wind than 2mm wire...
