Am I right in thinking that the Chappel actions of this period have the jack spring sitting upon a piece of thread . . . and that after 80 years or so the thread breaks?
Are there any technicians in the Yorkshire region who might be able to rethread the action and what might be the cost?
My grandfather had a Chappell of about this period, a baby grand probably shorter than 6ft. There was a terrible change of tone at the break. Does anyone know the 6ft model and does it display the same problem?
