where can I get 50-300 uH adjustable coils? Answered
I'm trying to build my friend a Theremin for Christmas (obviously wont be finished by then), and I can't seem to find a few parts for it.
Its a design that comes from Popular Electronics November 1967 Issue (http://bit.ly/gNaQVH). It calls for 50-300 uH adjustable coils and I can't find 'em anywhere.
I have found adjustable coils/variable inductors but I haven't been able to find any with this inductance rating.
Aside from building my own, I'm at a loss here.
