kt88 ( 6550) has less Ra and will give lower output impedance. This mightbluerondo wrote:Shuguang's El34 sound very good to me also but I don't have anything else to compare them with. I wonder how the KT-88's sound in comparison? I saw these Electro-Harominix (tubedepo) on Amazon for $63 pair. I believe they will provide more punch and less vintage tube-ness. I'm tempted to give them a try.
