 Could the hammershanks be hitting the spring rail?  Maybe a W..............console with excessively worn hammers or a misaligned spring rail is allowing this on a hard test blow.

Most of these I've ruled out.  The sound is similar to a key, struck hard, that had a thin card punching on the f.r., however, the sound itself, is in the action.

Tighten the screw on the action, hammer but screws, wippen screws. Check if hammer heads are loose or catchers. Check the bridal strap wires, are they clicking against their neighbor.

The other day, I did a 65 cent pitch raise on a W........ console.� Will return in two weeks to retune.� In tuning, I noticed a slapping sound�in�the action when I did test blows, actually any blow in the forte (f) range.� The dip was a little excessive, but the sound definitely was coming from the action area, not from the keys.� I checked with dampers off strings, also didn't see slapping jacks, and the action brackets were low and tight.� The sound was somewhere between a paper and a wood sound.� Any ideas?
Thanks,�� Gary
