Jim, Could it be that the key end felts are just glancing the damper levers due to severe action misalignment causing occasional knocking/ticking noises of key ends on neighbors' damper levers or keys getting held up by them. Only happens when the cheek block is in because the una chorda must be depressed to get the bass end cheek block in on this particular piano? -Mike Dang it, I forgot how to spell una corda.
