This is the Atma-Sphere MP-1 MK II preamplifier (the latest is
the MK 3.3). 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 several
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 also put in some new tubes in the phono section. That
is about $600 worth of work you get as part of the deal. It will be shipped to
you in the new ‘box system’ that they make for the preamp. I have sold more on
ebay than Audiogon. My username on eBay is tufwheel too. Look up my feedback here:

Please check Audio Bluebook prices for this preamp if you are
wondering if this is a good price...
