@samstonehill: Great stuff Cahlen! Awesome to see you jumping in with both feet and it was a very good idea to link Yannick's series below, which is in my opinion of the best series of films available on this subject. I watch every one twice! Can't wait to see your results and love that you are using vaccum cleaner power chords. I found an old computer monitor yesterday which today will become a Lakovsky coil.
