It's a trivial thing; I did it w/o schematic. 

On the usual sort of 70V line transformer, there is a hi-Z 
winding. That goes across the Line Out terminals. 

On the Lo-Z winding, there usually are taps to match various
speaker impedances. Choose the one that fits your speaker.

Simple. Easy. Even _I_ got it right, and that's saying something.
