1960s Vintage Grundig Concert-Boy 200

Hello everyone, over the weekend I picked up a 1960s vintage Grundig Concert-Boy 200 that is in pretty good shape overall except for a broken dial string and the previous owner left the batteries in the radio which of course leaked inside the battery holder and it pretty much ruined the battery holders.

So I would like to know a little bit more about this radio and how hard or easy it is to repair (I did see it has socketed transistors like some of the old Zenith Transistor Radios from the same time period.)

Also how good are these Concert-Boy radios, and can the FM band on these radios be made to receive the full 88-108 FM Bandspread that we have here in the US even though the FM dial only goes up to 100 on it?
