Hi Ron, I have seen the QT installed in a Petrof with Renner action, and spoken on the phone to the man ( Luc Giné) who installs them for the importer (De Groot in Utrecht, The Netherlands) of Petrof and other brands. It looked fine to me. And Luc told me there are a few things you have to consider first and one of them is indeed the space between the hammerhead and the damperhead screws that most be big enough for the stop rail. >From info I got from another source I now am at the point to consider the possibility of buying a Quiet Time GT 00 (that is a system without the syntesiser) and connecting it to a Yamaha MP50 unit. This way I can have a nice syntesized Yamaha piano sound for a reasonable prize.
