Mark you were right on.
The answer was simpler than I made it out to be.
There is a small cover on the light itself on the underside of the dust cover that holds the bulb. Once removed, the bulb holder itself slides back through the top of the dust cover and through the holes in the dust cover bracket.
I am removing the dust cover to replace the aluminum plate that somehow had something dripping on it that corroded the plate leaving a half-dollar sized hole in the finish. Unfortunately, I didn’t take any photos before I started.
The plate is now removed and I am in the process of cleaning and polishing the dustcover itself before replacing the plate. (Ordered from Beo-Parts).
Since this plate was in the worst shape, I started with the Beogram 5000 turntable before setting out on the Beocenter and Beogram 5000 cassette.
Thank you for the replies.
