Genalex Gold Lion KT77
The Genalex Gold Lion KT77 is a drop in replacement for any EL34 or 6CA7.
The Genalex KT77 sound however is not typical of an EL34 or 6CA7. It is more of a hybrid. The Genalex KT77 tube delivers all the mid punch you would expect in an EL34 but also has a top end that is more open and bright.
