I had not noticed this, thanks for bringing it up.
This is so interesting to me that I may buy a t61 or another r61 just to 
try it.
I have a r61 which is slowly going dim but I would have to to try this on
a more expendable one first.
I have replaced a few ccfl tubes in the past and it is not something that
I would really want to do again because it's just do difficult.
So I too would like to hear your questions answered.
