Accuphase C-280V Operation Confirmed

This listing is for the main unit only. The original box is not included, but I will pack it securely in a sturdy cardboard box.
I am selling this because I purchased a new preamplifier.
The unit powers on and operates without any issues, and there is no crackling or static when adjusting the volume.
While I haven't measured it with precise equipment, by ear, using RCA connections, I haven't noticed any volume difference between the left and right channels, and the sound imaging feels consistent. I compared it with other amplifiers in the same environment and found no issues.
When using XLR connections, white noise occasionally occurs from the right speaker.
However, with RCA connections, it can be used without any noise or other problems.
All basic operations were also confirmed to be functioning correctly.
I have photographed any noticeable scratches as much as possible, but please assume there may be others.
As this is a vintage item, we kindly request no claims or returns unless the unit is fundamentally non-operational.
Please understand that price reduction requests cannot be accommodated.
