Well it's good to hear confirmation that 6x9 works well on the lpl enlarger I have.
Btw what length lens do you print with? Right now I don't have anything longer than the 80mm rodagon that I use for 6x6. I was hoping i could sneak by. Do you use a 105mm? As I was also concerned with the thread size if larger than 39mm would not fit the lens ring/board with these longer lenses.
