Back when our club got it's TDC 116, the motor seemd a little sluggish
and I wanted to install double throw, double pole toggle switches to
allow me to turn off the bulbs and leave the fans running,   I took the
thing apart, lubricated the motor and did a pretty thorough re-wiring. 
While I was in there, I added a rectifier to feed direct current to the
bulbs.  I had the theory that that might increase bulb life.  
Now months have passed, the projector works very well and the same set of
bulbs is still going.  I don't think they were new and they have seen
heavy and hard use.  I'm wondering if anyone  else has done this
conversion and kept better track of the results than I have.  I'd like to
know if the rectifier is likely to be doing any good.
