Joule Ringer!

Believe it or not, when the media is talking about China as the world factory, I can't get a China made ferrite core that is fit for Joule Ringer as posted by lasersaber, I was told that China made ones are much inferior, they can't meet the high AL-value (nH/N2). That's so unfortunate.

Therefore a question: what is the original core in the fuji transformer? Is it also ferrite or something else?

Fuji has many different styles of transformers out there that are used but, all of the ones I am familiar with have ferrite cores.

Thanks. I might just grab an inferior one and give it a try first. With almost half Al value, the current consumption will double...

Another question: what is the core material used in the bifiler coil? I looked into a book, and it seems even a bifiler should have an inductance, maybe around 50 uH, depending on the core material -- in fact, everything has an inductance.

A bifilar coil may or may not have a core at all. It all depends upon what you are trying to do. Bifilar just means 2 wires wound together so core material can vary or it can be an air core also.
