Are the new balances the same length as old? Did you charge the balance with 2 or 3 turns? Did you lock spiral in the same notch as the old balance in pivot shoe? Something is preventing spiral from rewinding in tube as you raise window. Before reinstalling balance, hold balance in one hand and with the other hand slide spiral up and down in tube. See if it slides easily.

Can you un-wind the balance? Ten turns is too much and may have ruined them.
