Hi

Did you check the caps on the p/s with an ESR meter?
I had a similar fault on a set recently not the same make or model; none of the electrolytic caps were bulged,  I checked  all of the with a ESR meter found 2 of them where the ESR reading was well high I also checked the capacitance reading  and that was within tolerance changed them both and up she come.
