You are viewing an ARR P144vdg 2m preamp that I've decided to part with. I had originally picked this unit up for moonbounce, however I ended up going with another. The unit is in good condition with minimal wear and scratches. I'm see if ther are instructions for this. If there is, I'll included it. Thank you for looking and I'll pay for shipping.( most likely USPS Parcel Post.)
