The author's approach is not to cancel the inductance of the 0.2
Ohm (not 0.02) resistor but that of the 5 CM (2 inches) of
connecting lead.? Multiple surface mount resistors mounting in a
ring around the Hi binding post can make a much lower inductance
insertion point. Surface mount resistors in 0805 size are available in values much
lower than 1 ohm although it takes some checking in Mouser's
resistor selection guide to find a value available in qty 1 rather
than min 1000 in the resistance and case size desired.
