McCormack Micro Phono Drive Rev A

This is a McCormack Micro Phono Drive with a Rev A. I was told at SMC the only thing that could bring this to the next level is to build a new power supply. If this is done it would take lots of money to get something close. This has upgraded jacks and all kinds of new work inside. It is one of the best phono preamps I have had. It comes with the wall wart. It is from a non smoking environment. I want 600 plus shipping Conus. If someone had a phono preamp in the 200-300 range and wanted to do a trade and some cash let me know what you have. I might do something like that.
