In a recent post from Fighter, it was pointed out how it is hard to get a supplier that is trustworthy and reliable for Cores. The Hitachi Cores can be expensive and in some cases a bit different.
I created a Category: Amorphous Metal Core Suppliers
If you want to post your suppliers as a new Thread, and we can share experiences on the suppliers.
This might help get Cores at a good price from a reliable source.
