Hi Ric. Yes, the device is checking under more soft playing than the usual arrangement, even with the repetition springs kind of hard limit regulated. The backchecks are at 68 °. On this action, the only problem I had is that the regulation of the backcheck is not very continuous : I mean that just a little more higher checking is immediately too much, and a little lower is immediately way out. But just right is curiously evenly just right through all the scale. Like you, I never ran across another example. It sounds to me like a very good idea, and after all not that expensive to implement. Anyone thinking about possible drawback ? Obviously, even the durability is far superior. Best regards.

You say the thing checks not only quietly but solidly under all levels of play ? Cheers RicB Hi Ric. Here is a pic of that Rönish checking arrangement. The piano is from the 1920 and I have no reason to believe that what you see is not original. Yet, see the condition of the leather ! And this is in the tenor section, where you usually have the parts worn out. And the noise to catch strength ratio is the best I have ran across. Curiously enough, the rest of the piano is kind of cheap. Best regards. Stéphane Collin. Url : https://www.moypiano.com/ptg/pianotech.php/attachments/20070102/c09265cc/attachment-0001.jpg
