Sensor Arm Photocell for Beogram 4000, 4002, and 4004

• Replaces original sensor arm photocell in Beogram 4000, 4002, and 4004.
• Direct drop-in replacement for original B&O part 8760002.
  
• Most likely fix if Beogram drops the arm on an empty rotating platter.
• This post discusses installation in a Beogram 4000 (4002/4004 have the exact same setup).
• Photo voltage: ~0.45V
• Installation requires soldering/desoldering capability.
• Test the sensor signal with an oscilloscope before using the Beogram after implantation of the photocell. If no oscilloscope is available, test whether the Beogram recognizes the absence of a record and properly disables the arm lowering function. Arm should sweep the entire platter and return if no record is presence.
• If the sensor signal is weak after replacement check the bulb alignment. Bulb may also be weak.
• Beolover strongly recommend also replacing the incandescent bulb in the sensor compartment with the Beolover Sensor Arm LED Light Source for Beogram 4002, 4004 and 4000. This will result in a strong and reliable sensor signal.
