I am selling this item because I didn't use it due to a change in equipment. It has been stored in a dark room, but there may be minor scratches. However, it appears to be in beautiful condition! It has been stored in a warehouse for about six months. ⭐️ AK-280 Preamp - Unused (body only) Type: HiFi Power Amplifier Channels: 2.0 Material: Aluminum Alloy RMS Power: 40W+40W Rated Voltage: 12V/3A SNR: 90dB Resolution: 47K Distortion: 0.1 Impedance: 4-8Ω Rated Frequency: 20-20KHz Input Modes: RCA/Aux Size: 155x75x46mm *Please note that the adapter and original box are not included. If you wish, I can perform a power check. Since it is unused, I will not perform a functionality check unless requested. As this is a sale of an unused item, I cannot accept cancellations or returns after purchase, so please bid with your understanding. Please feel free to ask if you have any questions. Please refrain from purchasing if you are looking for perfection, as this item has been stored by a private individual.

If the item is out of stock, it may be canceled due to priority given to prior offers, so we apologize for any inconvenience. *Regarding packaging and shipping I generally pack items compactly.
