Clinical Electrotherapy - Dynatron 72" Combo Lead Wire, Stereo / 1 Pin 1 Banana : The Dynatron Combo Lead Wire includes a stereo lead wire with 1 pin and 1 banana. It is compatible with all Dynatronics equipment that uses the 1/4" stereo plug (non-conductive tip) on one end. The other end has one gold plated .08" pins offering superb conductivity. This wire is a direct replacement for the ones included with the original purchase of a Dynatronics unit. It is advised that lead wires be replaced every six months because of the high voltage transmitted across them. Replace lead wires if your unit is "shocking" patients (spikes in output), the unit is terminating mid-treatment, or if there is no output. This combo lead wire is sold individually.
