Tube Characteristics


Someone give me the quick and dirty on the sonic differences between: EL 34, 6550, KT-88/90. My current mono blocks are stocked with el-34's heard thru Maggie 3.6. Thanks

Down and dirty-34s are sweet thru the mids,top/bottom a little weak.6550-muscular but lacking in top-end delicacy.88s are my FAV-fairly full range-good performer all around.No experience with the 90s.

My fav is EL-34 and E34L tubes. KT90, KT60 are much harder sounding tubes, IMO.
