does anyone need a braun csv 60

i own a braun csv 60 amp that will not power up. it appears that the power transformer is not putting out any juice. I am the second owner and the chassis is clean and the cosmetics good. the amp has 4 new power tubes. any suggestions? the prior owner shut it down several years ago due to humming. he imparted to me that new power tubes was always the cure. There is voltage at the power switch , and 0 voltage at the power transformer.
Thank you
