ferrite quality?


Steve Ratzlaff <steveratz@...>
 

Hi Michael,
No, we don't know anything about the "quality" of any of the ferrite we've been using, that I know of. I don't know how one would determine "quality", anyway. I know that the ferrite I've been using, which is a combination of the NOS Russian eBay ferrite as well as Amdion rods.

Do we know the quality of the "vintage" Soviet ferrite?
The date stamp suggests older production. I once had
a transistor radio from the Soviet era. Sensitivity was
poor - it worked better, with an aviary of birdies,
with a longish wire attached :-)
