In Reply to: Pushpull output iron : any schematics out there for a split bobbin design ? posted by Al Noakes on March 14, 2015 at 14:08:22:
Check out DT Williamson's original article. He gives complete instructions for the design of his chosen output transformer which was a twin coil type as you are asking for.
Williamson's output had (by memory) a 10K anode to anode pri impeadance. But you (or your builder) should be able to ratio it down to 8K and get the right number of turns and calculate out the correct wire size.
If you could ever find some... the Freed QGA series were all built on EI's with a double (side by side) bay winding arrangement.
Good luck with your project,
