List....
Checking end point and linearity on a COSMOS is time consuming and
everyone I've done needs the one turn off the end point coil.--- until
now.
The last one I've just done was very recalcitrant and I opted to remove one
of the 10pf N300 caps across the main coil to bring it into line. One turn
didn't make the appropriate distance.
There 'appears' to be no ill effects --- endpoint adjust OK and easily
achieved linearity.
I realize that clever engineers spent time and money designing/proving their
product but what ill effects might accrue from this heresy and deletion !
I would expect temperature stability might suffer at extremes both + and -
Comments/dissertations welcomed .
