Hello, I have built a pedal that requires 15 vac , dual power supply, not vdc for power.  Does anyone have a good source for ac power jacks 2.1mm? I have not wired up an AC 2.1mm jack only have dc. Thanks!

A jack socket is a jack socket - doesn't matter if you put AC or DC through it!
Bringing you yesterday's technology tomorrow.

I guess I should have explained this in more detail. I realize a jack socket is a jack socket. I have a transformer that has a secondary of 24vac. The transformer has a center tap. I plan on wiring the transformer to have a cable with a 2.1mm "dc" or style plug on it to fit a "dc" style jack. I would like to wire the center tap so it grounds to the chassis through the 2.1mm connector instead of installing a large IEC style connector.

The transformer is too large to fit in the enclosure and being I have the transformer already I figured I might as well use it. I was going to mount it in an external box and run a three prong to the 120 outlet from the primary mains and the secondary set up as described above. Maybe I should just not use (clip) the center tap and wire the "dc" style jack using only the secondary mains.

  If putting a jack in, why not make it a DC jack..the transformer box probably has room for an AC/DC conversion circuit ?
 The transformer secondary and DC conversion can then be a floating voltage, ground loop.
  Making the DC conversion in the 'power box' allows the pedal to follow suit which is more common, although you would probably remember, having an AC plug that fits DC jacks, someone might help out by connecting AC to a DC circuit...instant damage.
Convention creates following, following creates convention.
