Hi Garth. I have no personal experience with the KT66, but one thing you could try is to go to
www.google.com and then click on the "groups" tab, then type in the search bar "alt.guitar.amps" and hit "enter" and then type in "KT66" and browse some of those newsgroup posts, or post your own question. You have to take everything you read with a grain of salt, and alot of the information is in the context of rock guitar amps like Marshalls, etc., but you may find some info and some interesting reading.

"he mentioned that KT66 tubes will work in the amp and give a dramatically different sound than the 6L6s that are currently in the amp."
Except for a miniscule change in power output (either plus OR minus), I am not aware of any sound "coloring" or dramatic difference in applicalbe power tubes.
Tonal changes are more acute to the preamp circuits than power circuits. That is why they are called power tubes. They simply drive the speaker harder or less hard.
Transformers, resisistors, caps and pots have a much more dramatic effect on sound (tone) than any power tube. This is why the "tonal" circuits are almost always in the preamp section of an amp.
In fact; everthing else being equal, Power sections of most amps are considered "flat" for all practical purposes; regardless of what type of tube or transistor is used. (Output transformers excepted)
Be leary of this type of "hype". Words and phrases are often used in a myriad of statements that have NO basis in fact by "good ole boy" techs.
