This part was removed from a brand-new mixer and replaced with a version compatible with European voltage. The board was previously sold, but it was returned after the buyer had performed unauthorized soldering. I do not know what, if anything, was replaced or damaged during their modifications. The part was brand new before the original sale. Because of the buyer’s alterations, I cannot verify its condition and I do not have the equipment to test it. It is therefore being sold as-is, for parts or repair, with no guarantees regarding functionality.
