OK, I might be over thinking this but I'm going to ask to check. I'm looking at a center tapped transformer (yes, from All Electronics) that is listed as 12.6VAC center tapped. The photo shows 6.3 - 0 - 6.3. If I connect from one 6.3 to the other 6.3 I'll have 12.6VAC, and if from either 6.3 to 0, then 6.3VAC. I need both the 12.6VAC and 6.3VAC converted to DC with a result of 12VDC and 5VDC. From the 12VDC regulator I will have 12VDC and a 12VDC GND. From the 6.3-0 connections to a 5VDC regulator, I have 5VDC and another GND. Are both the 5VDC GND and the 12VDC GND at the same potential? ie., are they the same ground?
The circuit being used to rectify the voltage is a single diode between the transformer and the voltage regulator (from Velleman kit K2639). It appears to me that the 6.3V terminal on the transformer that is common to both would be the ground. So the transformer would be better labelled 0 - 6.3 - 12.6 in my situation.
