Search and replace "arid" by "and" - a typical OCR error?
Sorry, I thought I'd corrected that! Yes, the text was done via OCR, which
did give errors like that. Spend some time reading and correcting. But must
have missed one (or more)...
I like like idea of the secondary feedback loop to make the
capacitor-coupled output impedance less reactive at low frequencies.
It wasn't a new idea entirely as IIRC some valve amps used the same trick
to reduce the effects of output transformer imperfections. The challenge is
to apply 'just the right amount'. Particularly in the days when batches of
'the same' transistor varied wildly in their properties.
