Hi,
I'm under pressure from the wife to cover up / box in the projector and not sure if 1) should, 2) what sort of clearance space to give it etc to stop anything bad happening to it. Suggestions?

thanks

Ceiling or floor mounted?

You can't just put a box over it and expect it not to fry. The higher heat level will reduce the lifespan of the components and cause it to drift more.

You need to take the hot air out. A fan/vent system is the usual way. Here's mine: http://www.curtpalme.com/Hushbox1.shtm
While it's not a G70 the principles are the same for any CRT projector.

Making cooling completely sealed from theater gives best result. I blowed cold air to projectors input grilles inside hushbox from room behind back wall with two 120mm 75CFM fans. Projectors own back fans were plowing hot air back to that same room. Projector had 2" clearance to husbox walls. Rear speakers are hidden to same structure at both sides of hushbox, that's why it looks "bit" bigger than normal hushbox.



I used foam rubber to seal lens openings and IR receiver.



Here's more about project.
