Carriage Position Sensor for Beogram 4002 (Types 550x)

Replaces photoresistor and light bulb of carriage position sensor in AC-platter motor Beogram 4002s (Type 550x). Uses a modern monolithic IR photo-interrupter based circuit for generating a clean digital signal for triggering 1TR17. Fixes carriage position sensor issues, such as not working auto-return after playing a record or broken/cracked sensor plastic housing. Built-in test feature for verifying proper detection of plexiglass 'ruler' markings. See this post for installation and more information. Installation requires moderate soldering capabilities: Carriage position sensor photoresistor and light bulb need to be unsoldered, and Beolover component needs to be soldered to existing solder pads. Use of a desolder gun is recommended. Follow us on the Beolover Blog for updates and info about our B&O restoration efforts.
