Ray,

The manual doesn't specifically say whether the primary is the top or the 
bottom coil.  In the BC-611-F, it is the top one.  There might be some logic in 
making that the standard way in which to do it, and it would make the secondary 
leads the shorter ones.  But that's only a guess.  In any case, inside of the 
can you should find a 1/4" diameter phenolic tube with two pie-type windings 
on it, one above the other.  Probably there will be four solder terminals.  
There will be a square phenolic plate at the bottom of the tube and probably one 
at the top.  The terminals are probably mounted on these plates
