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

My Compact 80's (wish I still had them) kt66's were replaced w Sovtek 5881's when I retubed after I had them about 5 years
(and only lost 1 tube the whole 8 years I had them).Loved'em.
