I'm having some difficulty getting a hold of some cores from Metglas.  I've spoken to their US sales rep, sent an email with details for the cores I'm after, still no reply.  I'll call him again tomorrow.

He had mentioned Elna Magnetics as a redistributor for Metglas - I called and spoke with EM's sales rep, who told me that they do not have ANY Finemet available, and that getting ahold of some is quite problematic, he went as far as to say I'd have to fax in paperwork stating I wouldnt use the cores for WMDs??  For the Metglas I was requesting, he said that he'd have a shipment toward the end of May, and that other orders would typically require a lead time of 36 weeks??

Is this what others have gone through?  How did JLN get a hold of his nanocrystalline cores?

I dont suppose any has spares they'd be willing to sell 

Try this site for Metglas film. You should be able to roll your own toroids from this material. Scroll down to Metglas. Ultra high permeability space age cobalt alloy (1,000,000+). 1 inch wide $2.50 per linear foot.

Also the Nanoperm core JLN uses from PCIM Europe:http://www.magnetec.de/pdf/pcim%202000.pdf

Good point! I'm ordering a core from them - which is great!  The only downside is, the ~2.5 inch core I'm ordering is fifty bucks and shipping to the US is fifty bucks lol

Ah well, in the name of research   Thats really super - I was getting depressed about the metglas/hitachi situation, I have my oscilloscope, function generators, inductance meter, 2"x0.5" neo disc magnets, spool of 26# wire, etc, ready - and then I couldn't get a core - so thanks for pointing that out! (excited, a bit).

Once I get the last puzzle piece in I'll be sure to contribute to the video saga.

Have you seen this link?  Maybe they also sell within USA?

While I endure the epic wait for my core to cross the pond and get to my doorstep, I'll get my circuit ready for its arrival.

I'm thinking of setting up a parallel resonant circuit to drive the coil - wouldn't that pretty much nullify most of the power requirements for pulsing the core?

Nope, had not seen that site.  I used to think myself a google guru, but I went through pages of google results and couldnt turn up distributors, I appreciate the links to these sites.
