They work great in my new Jolida JD502P...I talked to everybody except the janitor (unless I DID talk to the janitor) at Jolida before risking transformer meltdown and was assured it was fine...they do run hotter than 6550s, but sound more refined with seemingly more dynamic range and treble accuracy than the 6550s...not as much physical "tube glow" since the grids are less exposed, but that's OK. I now have the original 6550's, KT120s, and a set of new Svetlana KT88s (just got those) for the damn thing so off I roll!
