"Reality, I don't know, and simply place my trust in what I've been told by the distributor. I would think he has a reputation to uphold. And based on my dealings including warranty concerns, no issues."
I would take what your dealer says with a "grain of salt". He wont make any money telling you what are the limitations or point out the deficiencies in the product he is selling.
Regarding the ability of your amp to use the various types of 6L6 tubes, that is true to a certain extent because all those tubes have the same pinout. That means it will work but the amp and the power tube will not be optimized for each other. I have built a 6V6/6L6 amp that is single ended and has a switch to adjust the cathode bias resistor that corresponds to the correct current consumption for each tube type. In this case the power difference between the 2 types is most obvious but the sonics are little nicer with the 6v6.
One thing to check when running higher power output tube like kt90, kt120, etc. is the heat from your power transformer. I noticed in my amp that when running the 6L6 tube the PT was much hotter. If that is the case with your amp when you are tube rolling you better buy the "extended warranty" for that amplifier . good luck, Dak
