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

KT-90 great dynamic range, good low end, take a while to break in and bloom. Mids not as good as KT 88 but better top to bottom. I favor Electro-harmonix KT 90 over the EI KT 90.

Svetlana (original) are excellent kt88's. EH KT88 are very good .
Genelec KT-88s are the best but $$$$$!
Don't neglect to find better input tubes (e.g.6sn7s or whatever your amps use) - the new production ones are considered inferior to the old by a lot of tube rollers....
