I have in the past reversed the varactor,  grounding R2 to get a  positive 
tuning voltage from 1.5 to 12 Volt. Also brought out the 5.7 volt for  
reference purposes. That way every thing was positive. Is easy to get to. But  
now I have some very good units and I am worried I may change something and  
degrade performance. Any comments?
