Purchased over 30 years ago and used a few times. Stored at home. Selling to declutter. Please check the contents. When testing, I inserted a cassette and forced it to turn. It was working smoothly, but I handled the circular reading head's up-and-down movement roughly, and the spring came off. Please check the last photo. The spring and gear are detached. Initially, the level and counter were also working. Requires repair. I tried the remote control with batteries, but it doesn't respond. I will answer questions to the best of my ability.
