I am making a 12Vac to adjustable DC supply. The 120Vac to 12Vac transformer I have does not utilize a ground. The bridge rectifier, capacitors, and ouput all need a ground. What do I connect to this GND of the PCB? The ouput is DC and is variable 1.5V-12V, but it needs a GND. Should I connect these to earth ground out of a wall socket?
