    We have a cheap intercom, runs off AC power, via a transformer to the master speakerbox and via a speaker wire to the other unit. I am getting pop-pop-pop noise continually, any assistance in getting rid of this easily, as the connecting line runs between floors in a building, and if soldering in a capacitor is easier than shielding wires Id be happy, Id like to know how to shield the AC source and then the line in, ie-power and noise filtering.

    First isolate problem if noise comes from connecting wires of the building. Bring the other Intercom unit near the Master unit and connect necessary wire. If noise or popping sound still persist. Send the Intercom for repair.
