Ok I haven't scoped the signals other  than to collect thier peak
values but I will go back and measure the rise  times when i
get back to my setup.   What I will do is test several  machines
and see what is typical.  I do know from experience that
a  50 ohm input is better than 75 which makes me wonder
how much resistance is  in the ribbon cable and it's connectors.

Yes I am  "tuning" the gain pot for the dead band on
units i send out but I think  dropping a bit will make the
dead band larger and easier to hit leaving some  room for
drift as the components age.    I want to avoid the  need
for the user to open the enclosure to adjust something.
