Hi Group,
And Mr. Hacksaw in particular..
I have been researching for equalizer-inductors for my G14 lately - and it seems that there's some extremely efficient ferrite core material around.
E.g. Epcos makes ferrite core sets with an Al-value of 28.000nH/T2. That is a staggering 2.8mH for ten turns..! :shock:
Which means relatively few turns to obtain desired inductance. Which again means controllable winding capacitance. I use up to some 20H inductors, and these are actually possible to get working without too much trouble, using these modern ferrite materials..
So my question is:
:?: Can ferrite cores be used for audio transformers?
Has anyone tried? Is there any industrial examples of this?
Any guesses on possible bad side-effects?
We known that ferrite are used for tape heads, so it may not be an all-together bad material for audio frequencies.. Or..?
