I'm making good progress with this set. The Frame linearity has been considerably improved by replacing C99 in the linearity feedback circuit. The capacitor was a Wima 0.05mfd 500V component. Replaced by a Philips 0.047mfd polyester capacitor.
After fifteen minutes or so the width does come in from the sides. It's getting a bit late now so I'll return to the set tomorrow.
