Hi

This isn't my design originally. The 620 ohm resistor in question sources 
current into a diode stack. The initial current will vary more from the 
tolerance of the diodes than it will from the 1 ohm change ( or 6 ohm = 1%). 


<snip>

Maybe we should buy lots of diodes  to match them, they are relative cheap, also 
use extra care installing them. Using hemostats as heat sinks and just enough 
heat for a good connection do not want to damage/change them after the match.
