Grace Design Lunatec V3 Portable Microphone Pre-amplifier / Analog to Digital Converter

This unit was purchased new by myself in 2004, was used in the field recording live concerts until ~2012. It has been safely stored away in a closet since that time.

This has been recently tested and is in proper working order.
*Please note: This particular unit was made prior to the discovery of the digital output being 180* out of phase. This is an easy fix in post processing. I believe Grace will still RMA to fix this issue if desired by the end user.
I am 99.9% sure I swapped out the firmware chip when there was an update to it around the 2008-2010ish time frame.
This unit can run on 6V or 12V DC power, there are internal jumpers that can be changed which will effect the "battery low" indicator.
I am including a 12v 1a AC power supply. This is just a generic power supply with a standard barrel connector, I recommend sourcing one with a locking connector(switchcraft S760K). Same goes for using an external battery, a locking connector is recommended as the connection can be a bit loose with standard barrel plugs(bit too much "wiggle", and not very secure).

Physically in good condition overall, there are some marks on the sides, and top/bottom of unit from some right angle aluminum "stilts" that were used in the field to allow the unit to be run upright, while not straining the attached cables.
Otherwise just typical light scratches/scuffs/marks/etc from normal use/handling. Please see pictures.

Feel free to contact with any questions or requests for additional photos.
