SOURCE: Need Behringer Eurorack mixer power supply connector

Those were used for mic connectors at one time,,, they are related to the Amp 91-MC3F family of connectors and those are out of production and they are demanding $20 to $50 for one connector.

That is a ridiculous price and I would be tempted to swap out the connector for a more available design.

On eBay item 250401122616 is one but they want $13 pus $11 shipping which is a rip off.

These were used on some OLD CD radio mics.

There isn't anything in the power supply you cannot rebuild except the transformer.

BUT you should verify that something in the mixer didn't short out and damage the supply.

After you relace the smoked parts (likely the TOP245Y offline regulator chip is gonzo... then you use this trick to restart the unit safely:

Put a 60 Watt light bulb in series with the hot side of the input power line. I would recommend you use an ISOLATION transformer when working on the power line side of this for safety.
