Pacific Electronics Intercom Issues

Looking for any ideas as to why this 3 unit intercom isn’t working properly. Units cannot hear anyone or speak and the buzzer gives a humming noise when the button is pressed. Not sure if it’s an amplifier problem?? Using a Pacific Electronics amplifier AF-1000.

Welcome to the forums.

Typically that's what happens when the power supply fails. The filter capacitor(s) are there to smooth the power. Since that uses AC for power...... the power supply is inside the unit.

You've selected warble. If the warble doesn't sound correct.... that's a unit problem.
