Hi

This cap-coil combination was used in many Philco receivers, chiefly right after the war. It serves as an IF trap in the B- circuit. Chuck has an extensive write-up on this subject on his website:

In practice, you can usually eliminate the cap-coil combo by replacing the capacitor itself, leaving out the coil, with no ill effects. However, you may retain the coil if you wish.
