C100 & C104 are the input coupling caps and changing them to 1uF would probably not have any effect. The data sheet I have, dated 1974, recommends a 2uF input capacitor but a lower value is permissible if reduced separation at low frequencies is acceptable.
C105 is the filter capacitor for the stereo switch level detector. The application circuit in the data sheet has this as 0.25uF. It gives the time constant for this as C105 x 30k +/- 30%. I would guess that increasing it from 0.68uF to 1uF would marginally affect the speed of switching from mono to stereo and vice-versa.
In reality I doubt if you'd notice any changes.
