Marantz Integrated Amplifier PM-54D

This is a Marantz integrated amplifier, model PM-54D.

I purchased it at a local electronics store (now Edion) near my home when it was first released and have used it for many years (mainly for CDs). I'm not particularly an audiophile, and even now, nearly 40 years after its purchase, I haven't had any issues with the sound quality. However, my study has become too cluttered, and the size of the amplifier is no longer manageable. I am selling it to switch to a more compact amplifier.

Please check the images for the exterior condition.
There are scratches (mainly in images 12-14), some faded display text on the front panel (mainly in images 8-11), and some buttons with partial discoloration (mainly in images 1, 8, 9, 10). The connector panel on the back also has scratches and rust consistent with its age (images 14-19).

When the power is turned on, there is a slight crackling sound from the front right area of the panel (near the power button and volume knob) for about 30 to 60 seconds (this seems to be affected by temperature, etc.). The sound disappears after a while, but please refrain from purchasing if this is a concern.
As I have used it for many years, I have used contact cleaner on the volume and other controls.
