Hi, A little bit off topic, but maybe it helps somebody who has run into the same problem as I did. A few weeks ago the EST450 power supply of my Durst CLS450 colorhead died, as I was not able to find a replacement on the used market and a new one was above my budget, I built one myself. It is a 24V DC powersupply that drives the 250W (ELC) halogen bulb. The power supply can easily be adapted to other voltages and currents, even to different enlargers. If you like to learn more about this DIY power supply: just let me know and I'll send you the schematics and some explanation.
