RCA playback confirmed, wanted to leave the factory digital output in place so did not test optical, but the condition I received the unit in and the overall lack of grime I see no reason why it would not work as a transport! Well cleaned inside and out with dry compressed air. Removed surface scratches in LED Display and plastic on door.
Cleaned disc identification light and sensor. Dusted all grooves in CD platter.
Applied new "Super Lube Synthetic Grease" to gears. All gears for platter lubricated. Super Glued the platter rollers in place to prevent movement or breaking.
