This pair of Gold Lion KT66 output tubes replaced a pair of Valve Art KT66 where one shorted out in a JTM45 clone that I build and put into a 1x12 combo cabinet. They sound great and are shorter that than the Valve Art tubes so they fit better in a tighter space giving a little more clearance. I highly recommend them.
