What Brand of Kt66/6l6 tube was used in VTL MB-80s


I recently purchased a pair of mint VTL compact MB-80s with the original 3 page "manual". It stated the amp came with or it was designed with russian KT66s but the manual did not state the brand. The amp came with JJ 6l6s which sound fantastic, but I wonder what other types of this tube could or should be tried. Is there a difference between kt66 and 6l6 versions?? Thank you. Larry

I don't have MB-80s however, my VTL gear came with JJ electronic tubes. They are made in Slovak Republic.

JJ now makes a KT66

I think VTL used to supply Sovtek tubes which are made in Russia but I'm guessing.
