I have old sony G90 projector, because the green tube has worn out and serious burned mark, so I want to replace it, but I could not find the new or better condition P19LQF6 tube, could I use barco 1209's P19LCP07 instead of the original P19LQF6, or maybe use P19LUG to take place of it? thank for help.

P19LUG is pretty much the same as the stock G90 P19LQF. Most folks are just using P19LUG's for the G90 now because they are still in production from VDC and others. The LUG's were also used in some Baro models.

You should be able to get pretty much the exact same performance from the P19LPB03 as the LUG or LQF. The only difference is that the LUG has a scatter grid and the LPB does not, but that really doesn't matter. Other tubes you may consider include the P22 series, though I personally have not tried P22 in the G90.

Just do not use any LCP tubes as they will be very soft in the G90.

In case you need it, here is the pinout for several P19 tubes.
