Need Angstrom Owners Manual and/ or service manual

I’ve been using the Angstrom 200 for stereo off and on for many years and have never tried any preamp that I like as much. Mine finally bit the dust having lost left channel volume. I’ve not found a local repair shop willing to work on it without a schematic. I will keep searching for another one and, in the meantime, I purchased a used Angstrom 100 to use as a DAC only, assuming that the DAC circuitry is the same as the 200. I have the remote for the 200 hoping that the 100 is remote ready and that it, then, uses the same remote as the 200. So what I’m looking for is an owners or service manual or information on the 100, 200 and/or 205 units. I’d even be looking to buy another 200 if one becomes available. Thank you
