"No." Don't replace the springs only on account of this "non-problem." With the damper felt now missing, the BOTTOMS of the damper levers are limiting further head travel towards the strings by contacting the spoons and/or damper lift rod. Once you replace the felt again (assuming you shoot for thicknesses the piano originally had) you'll see that things work again with less re-regulation required. If you're still wondering about replacing the damper springs, however, Be guided by considerations of; old spring breakage, touchweight considerations, damping effectiveness [Ask Del Fandrich about this one,] and finally cost effectiveness of your proposed work over all. ... My 2 cents worth.
