I have an Alphasonik PMA800DA with a fried inductor.
Does anyone have the inductance value by chance?
This one is burnt so bad it burnt the via out and I am left with a hole to fix. The windings are charred black where its mounted to the board.
See Attached.

Indeed your were right Perry.
Both connections were broken from the board and I did have 1 severed winding I just patched up and heat-shrinked. After repairing the connections to the board, everything else checked out fine and the amp passed a bench test without issues.
I assume the lack of epoxy/glue to reinforce the inductor was the cause. Was a short easy repair though. I hate seeing inductor damage. I dread the day I am forced to rewind one.
