[Amps] Edge wound inductors

[robert briggs]

I have a quantity of these edge wound inductors ex old broadcast station 
equipment.Most were made by AWA.
They range from quite small, 30uh to more than 300uh.I have been able to 
use a few of the smaller ones in antenna matching networks, but the 
really large ones I haven't found a use here.I am fascinated by the 
construction of them and have often thought of cutting down a couple of 
the 150uh coils, making new spacer supports.However it may be a bit 
risky as once you loosen the supports you would possibly end up with a 
great bundle of  spiralling copper strap.
I have wrecked a couple and straightened out the strap to make copper 
clamps for GS-35B tubes etc.Very tedious but rewarding.
