Call the Fire Truck - 9VAC-2.1A Power supply supply help

[sampler1]

Hi all, happy New Year.

I picked up a lexicon I-onix U42S audio interface. As you can see in the photo ,we had a little fire. Also someone has been in here. on each side of the ground point some solder points have been added. I guess in a repair attempt. i looked for a schematic but nothing to be found and I need to figure out the voltage path. It would be appreciated if someone could help me out. The supply Voltage is 9VAC at 2.1A. I see there was some type of fuse F1 an inductor L1 and I guess C2. If someone could mark up my photo that would be a great help and also let me know what you would suggest for a fuse. I can measure the caps and inductor. I'm just not sure of the voltage path.

Best regards !

maybe I should clarify; I have no problem understanding a rectified power supply. Im trying to figure out the Voltage routing from the jack to the bridge. the inductors and caps are throwing me off.
Thanks

Kinda looks like somebody applied mains voltage to it!

Maybe not mains, but it's quite possible someone used the wrong voltage wall-wart.

If it was me, I'd do the math for the rectifier output and supply the right voltage DC to the smoothing cap to see if the rest of the beast still works. No point in going further if something major is gone.

As for your burned bit of circuit, the burned side probably looked very similar to the unburned side, with the inductors being used for filtering purposes.
