I have a Chromega D2 that I put a dichroic head on a few years back. Lately the prints were getting less sharp, and the cooling fan seemed to be on the way out as it was vibrating more than usual. I replaced the original fan with this one, which matches the specs of Omega's recommended replacement quite closely. I got it wired in fine, but as soon as I powered the unit back up, the fan cam on, but the bulb burned out immediately. There was significant corrosion on one of the pins, so I figured the socket might be going bad. I replaced the socket today, and it's still burning out bulbs. Has anyone had this problem or have any suggestions?
