Hi all,
Upon multiple occasions while designing circuits (mostly for audio use), I run into the problem of not being able to boost my signal enough before buffering/transforming it to speaker levels. That got me thinking, "if the <insert tube/transistor here> has a gain of <x>, then why isn't my signal boosting according to this?? In the case of a 12AT7, how come no matter what configuration I try, why can't I boost a 1v signal into a 60v signal? Is output impedance a factor as well? Any enlightenment would be greatly appreciated.
Thanks,
E
