Don, thanks for the suggestion. Trouble is the BC250L's grid/driver plate 
coil is NOT on a bakelite form. It is a ceramic one,  2 1/2 inches in diameter.  
I still get the exact same grid drive on 160 meters as I did on the broadcast 
band.  My problem still remains efficiency, and maybe I'll just have to settle 
with 61% and be happy.
