If you can't get high checking, it could be a geometry problem caused by hammers that are too short or backchecks that are too low. The deeper the knuckle has to press the rep. lever to get the hammer to check, the stronger the spring gets. If the hammers have been filed more than once or twice, that could be your problem. Several of the newer (1994) Steinways we have wouldn't check very high after only one filing just to the string grooves.
