I have found they are easier to change in this way:  heat the solder; when 
molten stick the point of an exacto blade into the mess of wires, including 
the one that may be from your resistor, or cap; continually twist the blade 
to loosen the wires; use the exacto point to tease the resistor's wire off 
the binding post or tube pin.....  usually the exacto tip will snap off and 
that is perfect because you are left with a stouter blade that will 
withstand the torquing of the wires.  If you want a point again just grind 
the back edge of the blade til you have a stouter blade with a bit of a 
point.   Works great!
