Oh well, the air core inductors did appear as too good to be true.
I ran the above coil at 440 W output for about a minute and shortly after that I saw the electricians tape melting, smoke, etc. As to be expected.
Onward and upward. The best approach seems an E core ferrite with a decent sized gap. Or a couple of Aerosharp chokes as Tinker is doing. wronger than a phone book full of wrong phone numbers |
