Description
New lamp for illuminating the fine speed setting dials in the following Bang & Olufsen models:
Beogram 4000 (some versions only – see EP-011 for more information).
Beogram 4002
Beogram 4004
Beogram 6000 (tangential models only)
Lamps are sold separately.
One lamp is used for each of the two dials.
This is a direct replacement for original Bang & Olufsen part# 8230052.
Note (!): In some Beograms, this lamp is also used for the optical carriage tracking sensor system, where it sits inside a black box at the base of the carriage.
Some Beograms have a soldered type lamp, others have a socketed type lamp for the carriage motion sensor system.
If your lamp is a soldered type, this is the correct type.
If your lamp is a push-in socketed type, you will need EP-089.
Tip: In cases where the tracking opto lamp is glued into the plastic housing, it is suggested
to drill out the old lamp and glue. It’s done from “behind” (outside) using f.e. a 4mm drill bit.
Any remains of glue are pulled out using needle-nosed pliers and any lead remains are cut away.
The leads of the new lamp is to be sheathed/insulated so they don’t short.
At the bottom of the lamps envelope, where its leads come out a small amount of glue is added, the leads are fed
through the hole in the plastic housing, the lamp is inserted and time is allowed for the glue to set.
Almost any hobby glue/plastic glue will be fine. Even a fast-curing epoxy can be used.
The gallery photos will give an idea of the procedure.
