My boss recently had me see this unit a week ago, it was dead set.Upon checking the power supply i found out that the capacitors ware the defective 680 uf/200 v.This unit is rated at 110 volts and i think it was put in the 220 v line.my question is, is it possible to convert this unit to 220 volts?if it is.what parts should be replaced and what would be the values? Thanks for any help, suggestions to be given.
