Paul,
I full agree with Roger :-)
I guess it's wonderful read the comments and replies to your,

When the bells will stop to ring I
will have a devoted folder to this question a maybe have an answer for
some devices that in the years lost their smoke stopping the service ;-

Other curiosities might be that my gate rise time is slower than
