Hopefully the power supply won't need too much work, but the "power supply can" does look like it has had its filter caps replaced in it at one point in time because there's a cardboard box style electrolytic cap  and a cylinder shaped one on top of the power supply can attached across some of the terminals on top of the power supply can.
