The bulb on the old Simmon Omega variable condenser enlarger in my darkroom just went out. I was just at the start of a print session and had just made three test prints. I had a sickening feeling when I poured the barely used developer down the drain... To add insult to injury tomorrow is a national holiday here in Greece and nothing will be open... and thus no Independence Day printing session...

I salvaged this darkroom earlier in the year and I have no manuals for the equipment. The bulb inside was a frosted 150W. Does anyone know if this a special bulb in any other way?
