Confused with 0TA3080

[Marc Nostromo [M-.-n]]

I did both. First the whole circuit and then not getting any output, I
tried the stripped version I referred to in my mail hoping to find if the
ota worked as expected.

Debugging circuits is far beyond my skills right now. But understanding
failures is why I do this too :)

you got the circuit completed, right?

there's negative bias feedback all over both stages, and may be necessary
for the otas to work, also including the resonance path.

(sorry not to spot this earlier)
