Sometimes electrolytic capacitors that are stored for some time will exhibit high leakage currents
. Before placing these in service, the capacitors might need to be reformed. This power supply can be used for reforming. Adjust R4 for the capacitor"s rated voltage and set S2 in position X. When Ml indicates the rated voltage, reforming is complete. For large capacitors, use position 2, and then position 3 after reforming starts. TX can be any transformer with a rating of 12 to 24 Vac at about 1A.
