I've owned new BAE preamps and would take these original 1073's every time over the new ones. It comes with its own power supply unit. The unit has no flaws except for very light rack wear.I have kept it in my smoke free studio it's entire life. So take advantage of my problem and grab one of the best 1073's! This is hands down the best 1073 made next to the vintage Neve 1073's. The item "Brent Averill 1073 Preamp (Rare-Original)" is in sale since Saturday, July 22, 2017.
