The square metal things probably house your IF transformers. Stay away from these. The filter capacitor is usually contained in a cylindrical metal or cardboard canister mounted atop the chassis. It will have from two to four sections -- I.E.: 40-40-60 mfd. It's usually best to disconnect this multi-section unit electrically (leaving it mechanically intact), and replace it with several modern individual electrolytic capacitors, beneath the chassis.
I had a Zenith 7H920 that was sounding a lot like the way you are describing. It turned out to be a defective tube: a 19T8 AM-FM detector/audio amp. I would definitely check out the tubes before going too far.
