Based on where the wires went, I am theorizing that the ac side is on the right, perhaps the red and brown wires...anyway, I assume I should test this beast before offering it for sale ot trade.
I have never tested a transformer, but i looked up the basic procedure. I have not found the color coding for the wires and am no good at reading schematics. Can someone more experienced direct me in the right direction...I have a tech friend who might check it for 10-15 dollars if it is too tricky, but I do have a multimeter.

Ps the receiver did not blow the main fuse when I initially plugged it in, it did nothing.

That's a power transformer out of a Marantz receiver.It fits a couple models but many of wires went to the voltage tap switch and all you have to do is find the primary wires for the 117v or 120v tap and hook a cord up those and see if you get voltage out of similar colored wires. Do you have a model number of the unit it came out of?

Mikey,

It came out of a Marantz 2245. A link to the 1st thread about an ABUSED unit is provided below.

Got it. His primary leads are on the right side of the way he has it positioned, posted on January 2, 2017 at 20:10:33

For 120vac operation he needs to tie white to brown and red to yellow and then yellow and brown will be his primary leads.
So twist the white and brown wires together and the red and yellow together and then take your continuity check between yellow and brown which is also where you hook it up to 120vac. The primaries of course will have the white and red wires hooked as well now.

Oh, yes, didn't mean to be cryptic, I meant to post this under the thread. This is the transformer from the previously amphibious Marantz 2245, which I am parting out now. Sorry about the confusion..

What's the claimed power O/P for the Marantz 2245? I ask because, believe it or not, it can be adapted for use with tubed circuitry. Magnetics are expensive and the money saved on buying a power trafo can be used, among other things, to buy the parts needed for the complex voltage multiplier supply needed.

Go over to the Marantz group at Audiokarma.

There is already a thread wondering if you're going to restore this.

Also there are guys over there that know these receivers backwards and forwards that are more than willing to help with questions.
