I had it in my head that the supplemental data applied to my set because when I first glanced at it, I thought it detailed the modifications made for the console version of the TV. So now that you mention it, I realize my set must not have gone through the "late production" changes, which is why the chassis isn't marked with "6DE6" so in retrospect my question was a little silly and therefore I retract it. I'm still very much in a learning phase but loving every minute of it!
Thanks for the helpful reply!
