This Lepai amp is used and in excellent like new cosmetic condition. It comes with original OEM power supply. Output: 13.5VDC, 3A. The power supply is tested and works ok. However, when plugged into the amp, the amp's blue light flashes and the green light on the power supply also flashes and no sound was produced. Close visual examination of the PC board shows no visible burned or broken components and the PC board is in very good and clean condition. The possible culprit could be the speaker relays. This sale is for those who are capable and willing to work on the item, either to restore it to working condition or for salvage the parts. The power supply alone is worth the asking price.
