For Sale: Demeter HPB-1 Tube Preamp
Selling my HPB-1 preamp that I picked up here on TB in March 2016. Great preamp with a brand new 12AX7 tube installed. The previous owner had the preamp completely updated with new chips and power caps by Jim Demeter.
Works perfectly with great tube warmth; comes with the Jensen transformer for the DI. Some slight scratching on the top and bottom, but otherwise in pretty condition. Selling because I only use my Mike Pope MPP-2 when I need a preamp and this fabulous unit is just sitting in my studio unused.
