[Amps] Hipersil, the myth and the truth. (Updated)

Will,
 
Can you think of a reason why, at least over here, the military especially  
seemed for many years to go for C cores rather than the conventional E and  I?
 
C cored transformers were always more expensive, and I'm told that a lot of  
mil gear was bought scrap for the transformers - saw up the windings, retrieve 
 the copper, and carefully keep and resell the pairs of C cores.
 
Come a long way froma bundle of iron wires dipped in varnish to make your  
own intervalve audio transformer!
