100% cathode feedback. It that the offical name for it?

Thanks!


Probably not - since there is no guarantee that the feedback is 100%... because
of the transfer of the transformer, I have no idea what the feedback percentage
would be...it would depend on the ratio... but I would guess it's a lot lower...
you would have to develop a voltage in the secondary to negate the cathode
voltage developed , or something... which I doubt is happening! And who wants a
zero gain output stage?? The only 100% here is the amount of current, not it's
effect.
