The bobbin size I wrote in the first post.2 3/4" od x 3" long with a 3/4" square hole through the inside bobbin.The outside bobbin is for the secondary wire.Each groove is filled one at a time.Fill first one then jump to second one and so forth.The smaller inside bobbin holds the chokes and the primary.The two chokes are wound at the same time side by side.You follow the same path as the secondary.Fill the first then jump across to the next and so forth.Then you wrap paper over top of the chokes, then you wind the primary on top of the chokes.This wire goes from left to right then back from right to left.One row at a time until you get what you need on it for your primary coil.Then this bobbin slides inside the outside.The bore of the outside bobbin will be @ 1 7/8" dia.All grooves will be 1/16" wide.The webs between the grooves are @ .070".As for the "X" marks in the VIC coil drawing figure 6-1,they only represent the area of the cavity to fill.Not any reference to direction or crossing of wire.Longitudinal wrap means left to right,and bidirectional means one way than the other(Both Ways).And yes the chokes need to be stainless,buy yours from dankie before it's gone.
The aluminum box it's in is the back half.Then the front cover as seen in the previos picture,goes on top of this one.The high voltage lead comes out of the hole and the input goes into the 15 pin block,and yes it's the same as a PC plug.
