I've been feeling a little dissatisfied with my Elmo ST-1200HD lately. When I show a black and white film, it's been more black and gray, and it seems dimmer than my ST-800 despite the more powerful bulb.

A couple of weeks ago Paul Adsett suggested that the Elmo slide in lamp socket was a lousy method of connection for the bulb and should be changed to a socket that enclosed the pin 360 degrees. My contacts were brown where the pins touched them, so I changed it, but that didn't improve things a lot (All due respect to Paul, he's still right about this...keep reading)

Steve Osborne's new website just showed up and there's a section on brightening your projected image. One of his suggestions is to clean your lens: not just the front but the back.

I tried this. I took a Q-tip and swabbed the rear element of both machines' lenses. Were they dirty? Let's just say there was stuff on that Q-tip that had it come out of my ears I'd be looking for a doctor now!

The difference it made was astounding in brightness, color and sharpness on both machines. I hate to sound like a detergent commercial but my whites have never been so white and my colors never so bright!

If you've never tried this, the time is now. You'll love the difference it makes!

All I ask is a wide screen and a projector to light her by...

That is very true Steve,it's amazing what these little machines
are capable of.A few months ago I related the experience I had in
projectioning a massive picture in 'scope on full brightness that
was astounding, (prime lens) and in my humble opinion, is as
good a performer as it's big brother the GS.Granted the image
was no where as good as the high power/souped up jobs, but was
still watchable.That is good advice on keeping the lens clean, but
be careful not to overdo it,as the bloom could be spoiled.
