Is there a good text to read that explains the idea of using feedback windings in output transformers? I know that the nicer Focusrite stuff uses feedback windings, as has some older Calrec stuff, and I've looked at schems (app notes) at Cinemag, Jensen, and Lundahl, but those don't really provide enough information to understand what all is happening in the circuit itself (either that, or I'm just slow).
Where can I go to learn more about this? I'm trying to put together an output stage using a drawing from the Lundahl tech sheet (http://www.lundahl.se/papers.html -- the "Mixed feedback.... " doc at the top of the list) using an Edcor XS1100 (their equivalent to Lundahl's 5402). The drawing give some formulas for determining component values for the circuit, but I think they expect a bit more of a working knowledge of transformers than I have.
Help?
Thanks so much,
JC
