Just about to finish it ... Can anyone help me whether the TL701cn op amps will work or not... Checking the datasheet of both (LT1056s and TL701s), found same config ... And also I'm having troubles finding the ECM-60PC-R Electret Mic ... Can anybody provide me the equivalent mic that should be suitable?
