I hope so, we'll see.I like KT77's in my Origin50H better than 6CA7's.
I also tried them in a DSL20H for a while, but liked the 6CA7's better with that amp.
Not a fan of EL34's either - not a tinnitus issue, I just don't like the tone.
The 77's have a stronger low end and still stay tight without getting flubby.
They might be good in the KK for some high gain with a little thump at lower volumes.
