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

[Carcia, Francis A HS]

Remember a lot of the mil stuff in the air is running at 400 Hz. Also the
environmental
testing may have been harder to pass with EI transformers. Maybe C cores
don't need to be potted to pas humidity tests. How about vibration testing
with a core having many layers
floating on 4 studs? gfz

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!
