Hi Guys, I have started to put together a 908 as a test jig to do board repairs and mods. The 909 main board and front tray fitted quite easily into the 808 frame. Mounting P18 tubes with 919 neck boards will take some fabrication. I am think of mounting the tubes level so the point directly at the screen at bench height. No jacking up the back of the projector. Does anyone no what the connectors are called or brand that plug into the neck boards. I may have to make some of these cables. Thanks, Greg.   |

You need to get some gear together and start fixing quads |

Thats right the pins are reversed between the 8 and 9 inch MEC tubes. I notice the RGB amp is upside down. Since you are building this set you can make room for that as the other two tubes will need to rotate. If they hit the convergence tray cover plate perhaps you can just turn the tubes over so the end stages are the right way up.

Astig isnt overly tricky on the 909 as it is, youd think itd be quite a pain, but ive not had a drama getting it accurate.
Setting the zone astig though ive found i get way better results setting electronic focus as sharp as posible and adjusting zones for best sharpness, then going between astig and focus til it is perfect. I pretty near get the same sharpness in the corners on my red and green as i do in the middle with that method.

If they hit the convergence tray cover plate perhaps you can just turn the tubes over so the end stages are the right way up. With raising the convergence tray cover up and cutting some off it so the tube is level (not pointing upwards) there is heaps of room between the end stage and the convergence tray. If I turn the tubes over the high voltage cap is very close to the metal tray and I would need to modify a lot more to mount the tubes. It could be done. Had a lot of fun with this today. |

Ill test the rest of these boards here and might hit you up for some repairs soon mate No Problem, Once the rig is up and running, repairs will be a lot easier. I will make some board extender boards as well. |
