Ok so i have a seleco 500+
all the tube have 4000hrs on them. I bought it off a guy a kijiji who had it set from what can tell form the memory banks and form what i remember when i saw his screen when i bought it in 4:3 had the raster well set and used almost all of the tube face.
I am thinking of switch the aspect ratio to 16:9 how ever i and worried how this will effect the tubes over the rest of there life? also how does running the pj in 4:3 but only displaying 16:9 content compare to contare to anamorphic 16:9 in terms of burn in? In other word is the part of the raster where there is black get worn evenly with the rest of the surfis
another question, i have seen people say that it is bad to run a CRT at its highest contrast, that it over drive the tubes. what does that mean? what is the highest level that is expectable it is ok to have the contrast all the way up if the brightness is all the way down?
Ok last question when focusIng my projector I notices that the blue tube could not be focus at well as the other tubes in my Pj, from what i have read the blue tube is the one that seems to degrade the fastest, is that why it is more out of focus? I have only tried to mechanically focus this PJ i have not played with focus pots yet, In the manual for this PJ i says not to tamper with them that they are set properly at the factory, is there any risk in messing with the focus pots. Also the pot seem the be all covered with glue i assume this was done my seleco however i dont know.
any help would be great appreciated, thanks

So run it as lightly or as hard as you want.
way out of my budget as a student
