In response to various posts please find attached a mic amp
which has seen volume production in commercial equipment.

Feel free to ask any questions / criticise whatever.

It's nice to see the diff-pair currents going directly to
the output opamp, with it's 6.8k resistors. But why'd ya
steal away loop gain so aggressively by choosing 680-ohms?
The opamp has not enough distorsion to his taste maybe.

IDIOT.

Wasn't expecting anything else than that splendid remark.

If you will insist on saying silly things !
