Ui-a in the telephone amplifier circuit is a high gain inverting voltage amplifier, which is inductively coupled to the telephone line through L1. The inductor L1 is a self-made unit with 250 revolutions, which is composed of enamel coated wire wound on the iron core. The operational amplifier receives several millivolts through C1, RI and L1 to amplify the signal.
