Inductors of 553 API EQ

2. I’ve got a friend’s PeterC 553 kit inductors and measure them. They made on a large Ш-type cores, very precise inductance value.

3. I’ve got a batch of a small toroidal amorphous cores that can be very useful on my long diy trip That type of core has a huge amount of permeability. For example, for getting 1H I’ve made just 150 turns of the wire.
As I have not so great experience in the inductors as I should, I would be happy to receive recommendations about how to make an inductor of the best quality based on this magnetic core.

4. My 553 investigation get a pretty good result and move me on a point where it’s necessary to experimenting with a real parts. So I’ve designed a simple proto pcb for testing a couple aspects of 553 eq. Will see.

No news on where it is possible to buy these inductors?

If you are talking about mine - I have a batch of a such cores. I should test them on proto board and then I can offer them on market.

Thank you!
