I've just acquired an old baby grand (DeKalb circa 1925) that is in OK condition, but needs some work. It's fairly playable now, but I do plan on getting work done on it over time.

One of the things that currently happens that definitely reduces the joy of playing is that after a few minutes of playing (using the damper pedal) there is leakage on all strings. Giving the damper pedal 2 or 3 quick "pops" sets everything back to normal for a few more minutes of playing. Once "reset" you can play without the damper pedal forever without encountering the problem.

Where should I look? Is it probable that it's a mechanism problem rather than some issue with all dampers?

If I've not given enough enough for you to help let me know.

Thanks,
Lloyd

It can be anything in the damper train from the pedal sticking to back action sluggishness. Even a few dampers hanging slightly can cause sound leaking.

It's best to call a tuner/technician, but if you want to try a fix on your own, start wiggling stuff and see what sticks. For example, pull up the pedal rod and see if the pedal pivots freely. 'Stuff like that.

If the problem seems to be in the interior, you might be better served using the services of a tech.

If the dampers seat ok with playing the keys and have a problem when using the sustain pedal - the damper lift tray has a problem - it may be excessive friction at the damper tray pivot pins or possibly a problem with the tray return spring etc. You should hire a tech to evaluate as this may involve removing the action.

The damper pedal lever above the lyre could also have pivot pin problems. This would also cause the entire damper set not to seat correctly.
