Guys, make sure you get the gamma corrected in these old units, they all develope a heavy gamma drop, its a very time consuming job to manually correct, but its worth it, just be carefull it will easy look worse as the adjustment points dont adjust the point you expect/ measure.
Have a X3 here that got a new ballaster and lamp, good internal cleaning, and calibration, it looks quite nice, running low lamp mode fully open iris on a 110" neutral gain screen, getting 11fl 18000:1 on off contrast and around 130:1 ansi contrast.
The X7 measures around the same, but is drifting more, so overall the X3 performs better.
