no rep on upright

[John Formsma]

Wim,
Is this a problem throughout the entire keyboard? Or just on a few specific
keys?

How are the jack springs?  If old, they might be so weak that in regular
playing, they wouldn't return the jack under the butt.

I'm not getting your meaning here: "...and the hammer butt gets caught on
the back check."

Did you check to make sure the jack is not being trapped between the jack
stop rail (or the back of the letoff rail) and the hammer butt?
