We report on electron energy-loss studies of Ca-doped YBa2Cu4Os. O I s and Ca 2p absorption edges indicate that there is almost no change of the hole concentration upon Ca doping and that a major fraction of the Ca enters the Ba site. This suggests that the increase of Tc upon Ca doping is not cause
