From talk electronics, we have a fine example of an Edwards Audio MC1 Phono Stage with the upgraded PSU1 Power Supply. The units are in very good physical condition, and in perfect working order. The MC1 unit is serial number 003, and the PSU1 power supply is serial number 53. A superb sounding phono stage, it is also very flexible. It plays both MM and MC cartridges, and settings can be changed by removing four screws, opening the unit and moving jumpers. A power cord, cable from power supply to preamp, and a copy of the owner's manual will be included in the sale. See pictures for further details.
We don't have the original box for these units, but we take packaging and shipping seriously. We spare no expense and use heavy duty boxes, several inches of polyethylene foam on all sides of the pieces, and use water activated, fiber reinforced tape on all seams.
