I am going to look at a Kenwood TL-922 amp with intensions of a possible purchase. Does anyone have any practical experience with this amp? What to look for as far as typical flaws, defects or oddball mods before I consider the purchase? The background history of this amp is unknown, so I want to be sure its in good shape before I purchase. I do know it has not been used for about a year.

thank you
