[Elecraft] Solder and flux

[Bob Nielsen]

Some brands of solder wick come was pre-filled with flux and have a  
waxy feel.  I recall when I was working in  an electronics lab in the  
1960s, we had little bottles of liquid flux with an eyedropper-type  
syringe attached to the cap.  It was easy to apply just a drop or two.
