Benny,

You are describing what I have encountered in a Vose & Sons Grand I 
service at a local church. Memory says there is some kind of general 
marking for a guideline.

Otherwise, extrapolate the situation. Using one note as an example, 
take the jack to both extremes where it is obvious what won't work, 
then adjust somewhere in the middle of that.

Based on previous posts of yours, I feel certain you are the kind of 
individual that can figure it out with no trouble at all.

Best,

Keith
