Transformer Stacked winding arrangement

For some reason I seem to recall that information is in RDH4 (Radiotron Designer's Handbook), which is out of copyright and available online. If I'm right, you'll find it in the output transformers section.

Thanks, I have a copy somewhere.....

Without looking at other answers, mostly it depends on what properties are needed. If high efficiency and high coupling are a target you tend to do multifilar windings; if independant tuning is desired (think [antique] IF cans) litz wire and other techniques are used; if high dielectrictric seperation (1.5 kV more) seperate bobbins are used; high MVA transformers other things are done.
