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. If
somebody in a programme walks from right to
left, he gets fatter. -J. ‘Nichols (Kendal, Westmorland).
You should check the PL81 valve and the com- ponents associated with the width and linearity
coils, 6.8kí2 resistor and 390pF capacitor.
