These "high quality" replacement parts certainly appear to be cored.
Perhaps the core is less permeable than typical speaker inductors ?

Seems I've read some misinformation regarding the 405 somewhere.

Thank you all. Because as a new member, my posted reply will be postpond for some while. But I'm keep on looking at the leads including this one started by my own.

Hi Ouroboros,

Could you help to look again if cores inside of those axial-lead inductors are looked like as magnetic material (like as black metal cylinder), or only a plastic cylinder?

Please be careful, don't take off the part nor break it. As much as having an idea, that's enough. If its core is only a plastic cylinder, then the inductors are still air ones, as which everyone likes mostly. But really it confused why it seems so small while it is a real plastic core

I've still got the old PCBs taken out of one of my 405s, so I'll try with a magnet to see if the core is ferrite.
