Pioneer A-004 AB class integrated amplifier. ・This is a used, one-owner item, sold as junk. ・During the most recent check, no sound was produced even when connected to speakers. ・Currently, the power lamp lights up (as shown in the first photo), but due to the above condition, we cannot guarantee it will continue to light up. ・Due to its age, there are scratches, stains, and dents. ・No accessories are included. ※Sound was produced normally when checked about a year ago, so we imagine that it may be repairable and restorable for those who are knowledgeable. Recommended for those who understand the nature of junk items. Thank you.
