It looks pretty clearly marked as 1uF - there can't be anything in front of the '1' as you don't get 11uF or 101uF etc.
If you'd posted a picture of the bottom of the board, we could see where it connects to, and compare that to the circuit - or you could simply do it yourself.
Presumably it's just a different revision of the PCB, which as I presume you know is the teletext decoder? - so not much use now anyway. Does the set work OK with it unplugged?, some sets do, some require wire links fitting if the board isn't there.
