Thank you for viewing. This is ART's Studio V3. I am selling this because I don't use it, although I purchased it used. Since there was no box or accessories, I will include a power adapter from Soundhouse. Operation confirmed. Non-smoker, no pets. - Model Name: Studio V3 - Type: Vacuum Tube Preamp - Output Protection: Output Protection Limiting - Input/Output Terminals: XLR terminals, 1/4 inch terminals - Power: With AC adapter
