The logic-board table said C1-C10 47uF and C11 1uF; the real 820-0260 list is C2 470uF 16V axial, C6 1uF 50V, C11 220uF 16V axial and ten 47uF 16V - the two axials were missing entirely. Removed R56 (no voltage adjustment on this machine). Added SMD leakage and trace corrosion detail, Ux8/F258 fa... undo
