I've tightened and loosened those big grey screw things before but ended up cracking one..Never messed with coils though but I have messed around with an old pair of headphones with speakers cut off and stripped the shield back to reveal the bare wires and just plugged em in to the amp and played a cassette through said cable and tuned the tuner to think it was 90.8 and shoved these wires into the long black things in the tuner and picked it up on another radio in the house which received the signal on 101.5...Twas pretty good after some more fiddling with the wires and volume n graphics and was a solid mono signal...Sorry about the novel.....

you can get 110khz filters off of ebay,
http://www.ebay.co.uk/itm/PACK-OF-5-MUR ... 35cbcf5a8c they cost abit more than other components, 5 for 7.99. You could get a soldering iron and do it yourself, my soldering isn’t up to much, but i’m usually get them out by heating them up or at least the solder, use pliers to pull it, the iron to push at the legs, then you install ic sockets and put the filters in. There might be someone on skywaves who could help you out, but what i'm saying is its not that hard, since tuners are quite big, its not like their small and have lots of surface mount parts, they can take the heat. Some of the tuners I got only cost 12, so if they where to get wrecked it wouldn’t matter so much.
Those type of grey black cores you talk about are very fragile, your meant to use plastic trimmer tool, but the tools don’t take much before they snap themselfs.
where you using your radio as a transmitter? It is posibble to use a local oscilator as a transmitter, transmit to a nearby radio, used to use them in the 90’s, sometimes I could hear them weakly at 500 meters away.
