I bought a radio a while back and it had this in it. A tobe Rf-2 filterette.
I assume this is a power noise filter? Anybody know how it works and does it do anything good?

Yea it would be for power line noise filtering if it was applied correctly. I have the 1932 Tobe book about their filters but there is not one on the list of products called RF-2 so it may be later than '32. That is why a picture would be helpful. Most radios had a capacitor of .01-.05 uF connected to one side of the line to filter out noise. The types used in old radios are known to blow up from time to time and now they make caps that are approved for that purpose specifically that have approval stamps on them.
