I suppose a DC power supply with a full wave rectifier, but without filter capacitors, should be adequate for general plating applications. If such a supply with a fixed 6VDC output is acceptable to you, then all you need is the transformer and rectifier.Electrolysis, so I need a minimum of 3 amps and 5-7 volts dc. My secondary provides 14 Vac and the center tap provides 7vac.
Should the 7V winding with the bridge rectifier not deliver full 3A at 6V, you could use the 14V winding with centre tap and only half your bridge rectifier to get double the current at 6.6VDC.
