I want to experiment, my 6L6's are rocking, but I want something different. Im a tinker'rer
What effect do you think sticking some 6550's or some KT88's in a Powerball would have? My knowledge of the subtleties between these tubes and 6L6's...
i know about biasing etc, so I should be ok with that aspect.
what sound qualities does each tube have over the others?
