Not really a big mystery, but I found this in a box of stuff, and while I believe it is an "Active Tracking Filter" from the searches online, looking to understand what it might have been used for.

There is a hot and neutral in and out, but no ground connections. Simple, but robust noise filter? I'd expect a ground reference if it did anything with spikes or surges.

Looks like a fancy noise filter... might be useful.

Reduces unwanted noise and applies maximum attenuation to destructive or spurious transients.
Manufactured mid 1980s thru 1990s

Seems to me that equipment should be designed with circuitry immune to line spikes, etc. or have transient protection as part of the equipment.

Having to provide external protection is, to me, like buying a car with tires but with no air in them.
