If you want to add centering here is an old Zenith trick...On their color roundys they simply added movable magnets inside the deflection yoke (there were little fishing line wires that the service man would pull on to adjust). If you place a strong enough magnet in the right spot it will adjust the vertical centering.
On some circuits there was a centering pot that added a DC bias to the secondary winding to achieve centering.
