This Filter choke can be prone to fail in the a fore mentioned Collins receivers.

 When this happens they no longer filter the Hum in the audio properly, and you can hear this in the speaker when you turn the volume down.

 Assuming the electrolytic capacitors are okay, the L29 choke is likely the cause. As they age the go out of spec and no longer filter the audio properly

 This choke was recently purchased and was not needed. It is new in the box!
