This is the Atma-Sphere MP-1 MK II preamplifier. I bought this directly
from Atma-Sphere several years ago. They had installed an extra set of single
ended outputs so that this preamp could be used as a review sample. The power supply
faceplate has a small dip in the surface, which I had repaired by an art
restoration company. I have high-resolution photographs so you can see
exactly what the preamplifier looks like. While cleaning the unit I
accidentally damaged the volume control. I sent the unit back to Atma-Sphere and
they have replaced the volume control along with a full electrical check out. They replaced a couple of filter capacitors in the power
supply and installed some new tubes in the phono section.
