I did post the links... if you look at my post carefully, and move your mouse over "link" that's the link...there are 3 links in my post, but for whatever reason they don't really show up as obvious links!

Ah yes... Silly me...

Very impressive. I want one. While waiting patiently for Grant to return my PM regarding costs, etc., I spent some time cruising ebay. All the units look the same, though there is one with a "separate head unit" that claims some benefit from this ( 15KW on ebay ) so I guess there are some differences. Here's a link where the claim is 3000 sets made a year, and a price of only $1200! Also of interest, one of the sellers has a user's manual available for download. The more I google though, the more I think I should just wait to hear from Grant, :-)

Could you post the link to the user's manual?

<snip> I'm a theoretical genius in the use of induction fields <snip>

I just realized that could be taken two ways... Either I think I'm a genius, or I'm a genius
when it comes to the theory... You can pick your own explanation...

Frequency runs about 30,000 - 100,000 Hz.

Sorry for posting that question... I was just cruising on a different thread and saw that you had already answered it.

Follow-up question: how is it self-tuning? Is it based on feedback from the coil? I'm assuming that it tries to insure
that you don't get current cancellation in the piece being heated...

Again, forgive my questions. I'm a theoretical genius in the use of induction fields in industrial metals processing
but this is the first time I've thought about the nuts-and-bolts aspects of how these go together.

What is the frequency of the AC current in the coil with this thing? You said the transformer steps the current up to 1000 A?
