Aircraft Part King Air KA-90 Transister Assembly 50-364308-61 QTY 6

These assemblies were purchased from an aviation surplus sale. I do not know the history of them. They are in good cosmetic condition. It is marked, "AR, N712DB, KA-90". These unit are packaged as if they are all from the same aircraft. I am not able to test them. It only comes with what is shown in the pictures.
