Suspect that there might be an issue with some of the other caps as well, i.e the larger 2200uF 200V. Anybody else having this kind of symptoms and have replaced the big caps? Or is it more likely the other remaining smaller caps that cause the problem?

FIXED: Replaced the 5 small caps C504-C508 and the hum problem disappeared. Was planning to also replace the larger 2200uF caps but I had unfortunately ordered caps with too large diameter (35 mm), installed version is 30 mm. in diameter.
