C97 is the line flyback tuning capacitor. It is almost certain that it has developed a leak, it is now rather hot and there is wax oozing out at the ends. The set continues to work except the flyback pulse at the collector of the "upper" line output transistor now down to 55volts.
C97 is 0.17microfarads. The replacement will have to be made from capacitors of various values to get something near the correct figure.
