Sourcing EI core materials

[Chong-Han Gan]

I have been rolling my own power transformer for my tube amps. I am venturing to roll my own output trans. I am unable to source/locate any local supplier that can supply me nickel and silicon steel grain oriented lamination for my project. Appreciate any Intenational members can help or let me know where there are supplier that are willing to supply in small quantity in the region of 10 - 50 kgs. of lamintion materials.

I'm having a hard time myself doing the same thing here (Argentina)... you have two choices: either locating an electric materials importer or a cheap old transformer and removing the laminations from it. Local transfomer shops here don't sell cores; i still have to check on distributors to see if i can find anything.
