Here is some service information to keep your Wico OC in fighting spirit. When in any state of repair they were quite hot and reliable.  They suffered from the usual woes of dirt, wear, moisture and neglect.   Like the model EK, always check the condenser for electrical leakage.  Early devices used paper for insulation that likes to soak up moisture and break down.  Here is some information from a factory service manual by kind permission from Wico to help keep yours alive and well.
