Well......here are a couple of threads that are PP-UL KT88, 4.5 K output trans 60W but are using negative feedback. If you wade through the posts, there was discussion about using 6DJ8/ECC88's here and there.

They are both based on the Mullard 5-20; the Opus uses MOSFET followers for additional goodness........

"Mullard 5-20 KT88 PP blocks!

OPUS 5.0 A Modern Mullard
