There are 'step-by-step' instructions available in each lab to assist the users. The main duty of the capacitor filter is to short the ripples to the ground and blocks the pure DC (DC components), so that it flows through the alternate path and reaches output load resistor R L . Remove the capacitors from TP17 but keep the wire jumper from TP17 to TP8. In any case, the output voltage of a center-tapped full-wave rectifier is always one-half of the total secondary voltage less the diode drop, no matter what the turn’s ratio.
