Hi Jeannie, Could Mr. Walter have specified a hard felt for the capstan contact material? It makes for a 'no-wasted energy' resons to touch, but a nosiy release. Kind of like stiff schocks on a sports car...great cornering ability, but with the price of a bumpy ride. I test for that (hard capstan contact felt) problem by... -Holding down the key, (behind the balance rail) and with the hammer out of the picture, lifting and droping the whippen (from the jack toe) onto the capstan, to see if I can duplicate the sound. Let us know your result. Dan Reed Dallas chapter
