After many years of service, I would be inclined to replace all the electrolytics with modern components. They are the most common cause of integral switchmode supplies in brown goods letting out their smoke. If I was refurbishing a dead linear supply of that vintage, I would ask myself "What could have caused this failure?" and I'd look very accusingly at the electrolytics.
