And please take on board that the FED projector was BANNED in the UK on 
electrical safety grounds. And it wasn't worth the cost of bringing it up to 
spec
for anyone to continue importing it :-(

The BEST way to adapt this projector is to completely re-think the internal 
electrics
and install western standard components. The optics are OK - though the 
polarisers 
are oriented in a non standard way, so you can't use standard polarising 
glasses...

I can't remember off the top of my head, but I think it uses mains voltage 
bulbs. Don't
think there is a fan (it's based on the Belplascus which certainly didn't) so 
watch out 
for fried slides.

So. I would replace the existing bulbs _and their holders_ with ones that are 
suitable for 
use in North America. And I would use heavier cable throughout - the 
electrical current
to the bulbs will be doubled, and it's current that heats the cable, and the 
voltage drops 
as it does so because of the resistance in the cable. So, you get a fire risk 
and dim 
projection for the sake of a little cable...

And finally MAKE SURE YOU EARTH IT!!!
