Hi there, Firstly, I'd like to say a big thank you to Alan and Kim at Owl Video. I ended up with the Seleco 150 which Uncle Eric auctioned off for GOSH a few months ago. Unfortunately, by the time I got it, it had failed, but now thanks to Kim's diagnosis I've managed to repair it. The plan is to use the 150 to "test the water" of crt - and then look to upgrade to maybe an 8" later in the year. (my other proj is 1024 x 768 DLP - which is much sharper but personally I find the rainbows distracting) Anyway, question for you lens experts, the 150 looks a bit soft to me, I've focussed it as best I can, including the electrostatic pots, but even the test grid didn't look pin sharp. It has Delta TAC 3 lenses - are these the plastic ones ? Is it possible / worthwhile upgrading the lenses on this "starter" proj ? best regards, Paul.
