[LargeFormat] Power supply for a Durst 450 CLS head.

While it won't fit in the same place, you might want to look at Variac 
auto transformers.  They come in sizes from 3.5A to 30A and run on ebay 
in the $20-$40 range for the 10a 20a sizes. If you add a $4.00 bridge 
rectifier on the output you'll get 24v DC which will extend the life of 
the lamps by 2 to 3 times and it should only cost you about 10% more in 
power used.

Other (more expensive) places to look would be RS electronics.  Just 
off hand, what does a Chromega power supply give?  I'd think they would 
be cheap these days. Okay cheap to buy, not cheap to ship.
