Yes, most probably you're right, see my suspicion regarding the bulletin. Maybe Yamaha somewhen noticed that the factory parts turned out to be of minor quality. The repair service charged € 330.
Edit: These electrolytics most probably are C88 through C99 in the PSU section on Function board 2, page 68 in the SM.
Best regards!
