I would look for a spike in the voltage supply to the enlarger.
I don't know that a voltmeter would be fast enough to show a voltage spike.
Is there anything odd with the stabilizer unit? Do you have another
stabilizer to try?

Folks, can anyone help me troubleshoot reasons why my lamps are
blowing out within a few seconds of turning on my Dichro II color head
(on a D2). I'm using the standard D2 power supply with stabilizer. The
stabilizer fuse is intact. The power cord is plugged into a surge
protector via the timer. My house has always had a stable power supply.
The bulb elements are breaking. The problem began immediately. A bulb
I had been using for a couple years fractured. When I put a new one
in, it burned out within seconds. I repeated this with a new bulb and
the same thing happened. One bulb actually broke the reflector in the
process, but I'm not sure it was caused by the same problem.
I have a voltmeter to check current to the socket if you can help me
understand what I might be looking for in isolating the cause.
Thanks in advance.
Jim
