Duvetyne is a black, non-light-reflecting material that you would use to to line the inside of your RPTV. It's purpose is to absorb any stray light that may normally bouncing around inside your set...specifically to keep the stray light from reflecting onto the screen. It can be applied in a few different ways.
It can be glued in, it can be stapled (if you set's cabinet is made of wood) or it can be taped down. In the case of staples makes sure to later touch the staples with a non-reflective black paint and in the case of taping make sure to use Duve-Tape. These might sound nit picky but why go to all the trouble just to leave some little sparklies in there?? :cool:
As for how you would use it...the simplest explaination would be to imagine that you are going to detail and recarpet the trunk of a car. For the MOST complete job you would want to cover the entire inside of the RPTV light cavity, with special attention to any light-colored or metal pieces. These are the most refective.
And after all the flat and easy-to-cover surfaces are done then you could fashion a wooden or cardboard box to cover the lens cavity (box covered in Duvetyne, of course.
Ultimately the inside of your RPTV should be a black hole, with only the 3 CRT lenses exposed and the mirror. MAKE SURE not to block ANY othe light path and don't forget to Duvetyne the back side of the screen stack frame. Might as well since you will likely have remove the screen to get in there anyway.
So far all I have done is the flat and obvious metalic areas (which completes 90% or the coverage with about 30% or the work) and there has been a VERY noticable and worthwhile improvement in black levels and appearant crispness. I find that the focus and convergence is now much easier to accomplish.
Of course make sure to cover the CRT lenses and take special note of the mirror while you are doing this...no point in damaging something while you are in there
