This is my first post, and I'm a beginner.  I got this radio out of a barn loft and I'm guessing it hasn't been used in 30 to 40 years.  I opened it up and saw that the speaker cone had been eaten out and a blown capacitor was hanging loose.  I decided to restore this radio.  I replaced all of the paper capacitors with new modern capacitors.  I found a used speaker on ebay which was the same model.  I just got finished with it and turned it on and to my joy it warmed up quickly and I started receiveing stations right away.  My question is, is it normal in an old am radio to get signal bleeds of other stations trying to come in on the same frequency?  I live about 35 miles from a big city and get some of the stations very strong, but with other stations being lightly heard trying to come in on that frequency also.  I've picked up stations in other states also, with the same problem.  I have not done anything else to the radio other than clean the tuner with contact cleaner.  It was dirty and a little corroded.  When I rotate the dial, it moves freely after using the contact cleaner.  The sound is great and nice volume without distortion.
