BBC -1 and ITV give no trouble, but on BBC -2
there is a weak raster and barely discernible
picture which is too big for the screen. Manipulation of the controls slightly improves the picture
but not to a usable degree. Increase of the brilliance control causes the picture to start disappearing from the centre outwards. The picture also
stretches to the left giving a ghost image of the
missing part of the picture in mirror form at that
side of the screen. The sound is OK apart from
being “slightly out of tune “. -P. Ryan (London,
S.W.8).
We would advise you to change C128. This is a 0.12µF 500V capacitor between the line output transformer and the system switch to the deflection coils.
