VOX amPlug 2 AC30 Headphone Amplifier I purchased this new with the intention of using it as a monitor when checking wiring, but I rarely used it, so I'm selling it. There is no box or instruction manual. Only the unit itself, as shown in the image, is included. I checked the sound, and I think there are no particular problems. Batteries are included, but they have been used, so I don't know how much charge is left. Thank you.
