I'm trying to use a transformer to power my new D-TPA-Killer based amp. I'm using the 12Volt AMVECO 62032 transformer (digikey# TE62032-ND):

I hook it up in the standard way(?) for 115V wall power:
yellow and red connected together to one side of the wall plug.
black and violet to the other side of the wall plug.

At the amp I'm connecting green +12v, blue at -12v and red/brown connected to amp ground.

But my voltage levels are no where near what I expect. Before the diodes I have 32V/AC measured green wire to blue wire. After the diodes I'm getting 41V/DC, measured from I expect to be +12v and -12V.
Not that it should make this much difference, my wall power is 120V/AC, not 110 or 115.

Did I pick the wrong transformer? Did Amveco screw up?

Thanks...

Sounds just fine from here, you are measuring from the unregulated side

The values are a little high because you aren’t putting any load on the transformer but nothing to be alarming here

Also the values I got for the regulator don’t have an exact +/-12v output, more closer to 12.5-12.6v but this isn’t a problem either

Great, I'm at +-12V after the regulators, so I guess I'm ok...
