I'm a new proud owner of a Sony 1271QM CRT Projector, which I've read an awful lot about before I bought it. Unfortunately I'm having to work this in reverse; the Throw Distance is fixed but my Screen Size isn't. I've stabbed loads of figures into PJCalc and managed to get the right screen size for my throw distance, but it says I need "S" CRT Spacers. I believe from reading the manual that I can change one set of spacers by rotating them, but the other set I'd have to change. The projector currently has "M" spacers in it, so I suppose I need to change them. Does anyone know where I can get them from? I notice that projectorspecs.com has some listed, but does anyone know anywhere in the UK?
