#20 enameled wire.Sounds like a standard induction coil.
RadioShack used to carry such things.Doubt if they still carry it though.Any
electronic supply house should carry it

Hi OMs
I found a schematic of a 50MHz-preamp,and the coils are e.g. 5 turns of
wire
No. 20.What's wire 20 in mm,or does a list exist ?
