Omega enlarger blowing bulbs

[meganbrantley]

I've got a 'new to me' Omega C760 Dichro. It didn't have a bulb when I got it so I ordered a couple of ESJs that were labeled inside the machine. They blew pretty quick. I put a meter in the socket and found that it's putting 120 volts to a bulb rated at 82 volts. Is that the normal voltage? Is there a transformer between the outlet and the bulb that's faulty? Any help is greatly appreciated. Thanks!

Mine has a small power brick that goes between the bulb and the timer. Beseler has a circuit built into the head.
