Hello John
If you decide to put on the air I have number of manuals two for 
the 618t and one for the whole system which is a Collins manual show the cicuit for 
big green box which is called a MRC-108, I used to have a 618T3B which is
100Hz channel steps, but I sold it in moment of weakness. The manuals I have 
are for sale.
