I`m so glad you said that, plain magnet wire is so much more plentifull and cheaper.
I have seen small inductors that look a bit like resistors, one chap on here (Variometer I think) mounts them in glass fuse cases, I was wondering if I bought a load of those and wired them in series if it would have the same effect?
and what sort of Total value I would need to be effective (it neglects to mention it in the book) although I expect it would be in the region of Mili henrys rather than Micro Henrys and would probably end up having to buy a shed load of them anyway
