The trouble with this set is pincushion distortion, which is
most pronounced at the top. Adjusting the associated
controls 8362 and L125 has no effect on the picture
geometry at all.
First check for dry -joints (under the transductor, and on
the print connection to pin 1 of the line output transformer).
R362 or R364, which are in series across the transductor,
could be open -circuit, or the transductor itself defective.
Once the cause of the trouble has been put right, adjust
R362 and L125 for optimum picture geometry.
