STELLA ST6417U
This set has a line linearity fault on which the
control has little effect. This takes the form of
stretching on the left hand side of the screen. -J. Nichols (Kendal, Westmorland). Check the PL81 valve and the components
associated with the width and linearity coils,
especially the 6.81d2 resistor and 390pF capacitor
