Can you confirm you’ve replaced the boost HT reservoir capacitor, C105 (0.22uF - use a metallised Polypropylene film type) and both of the S-correction capacitors C107 (0.1uF on 625) and C108 (0.3uF on 405). The values of the two S-correction capacitors is critical.

Is the HT supply to the line output stage now correct?
