Pioneer SA-4000

I enjoy disassembling and performing light maintenance on used audio equipment as a hobby, but I am very old and an amateur. Returns and exchanges cannot be made even if there are defects. I cannot answer questions beyond what is written regarding maintenance details or operating status. Also, I will not respond to inquiries about the condition of parts after shipping, so please ask questions before purchasing if you have any concerns. However, I cannot guarantee answers to questions like Can it do XX? so I will not answer them.
I believe there may be scratches not mentioned and insufficient descriptions, so I hope you will consider carefully before purchasing.
Please prioritize the photos for condition and description.
*   Sound output was possible via external input.
*   Sound output was also possible via PHONO (MM), but only for a short time, so I cannot confirm if it is normal.
*1 Volume and capacitor have been replaced, and the input selector has been disassembled and cleaned. Considering its age, I personally think the exterior is relatively clean.
*2 I cannot negotiate prices as repair parts and shipping costs are required. I do not hold items or change shipping methods.
