Amorphous core material

I'm wondering if anyone has any experience purchasing and experimenting with amorphous core material. I searched the net, but could'nt locate a source. K2

you might try kevinc at K and K audio or whatever that place is.

Kevin of K&K actually hangs out around here, so he'll probably stumble on this thread before too long. :wink:

Indeed I have.

Lundahl buys a few different types of amorphous magnetic material for their transformers. They use a high permeability cobalt-based material for the small signal trnasformers and a "normal" mu iron material for the large signal tube transformers. I am not involved in the manufacturing, so I have no idea where they get them, but I am told by others that some of the US manufacturers have standard lams available in both nanocrystalline and amorphous materials. I don't know who they are, though.

Hitachi/Metglas (ex Honeywell) is the prime supplier AFAIK
