Hi!
I few weeks ago i projected this circuit, which you guys helped me debug (it had a offset problem). Today I built it and while testing i noticed it was attenuating higher frequencies of the audio spectre (I audio tested it as I do not have an available oscilloscope at the moment).
Can you please help me out? I don't seem to be able to spot the problem.
Multisim says it should have a flat magnitude from +-10Hz up.
Thanks!
EDIT: The "source" circuit is the one bellow.
