That double coil choke looks like the ones you find in old computer CRT monitors (which makes a good source of useful caps and resistors and such) and PC power supplies. Its purpose in the power supply is to cut down the leakage of RFI from the switching circuits onto the powerline. It may help to keep RFI out of a radio. I used one of these to impede the RF signal from a very strong local AM station from coming in on the powerline (I was getting "modulation" hum, when the RF sees a differing strength path via the power supply rectifier diodes, as the either conduct at the powerline peaks, or not conduct at the other times during an AC cycle). Just be sure you don't put one of the two coils across the powerline, it's not a transformer for 60Hz. Look at the PC power supply or PC monitor you pulled it from, you'll see how it's wired.
