[Boatanchors] BA Resistors

[jeremy-ca]

I dont know why some brands change value more than others but I doubt if 
moisture is the only reason if at all.

Perhaps someone knows if the manufacturing process involves patents 
regarding the carbon molding. I suspect that a chemical reaction is a more 
likely suspect.
