You can find schematics for the 350-B, C, & D at HHScott.com. You MIGHT also be able to find a manual at the same site, via this link, if you have Java Runtime Environment installed.

My problem is that I don't have enough neutral between the tuner and my DAC. They're somewhat close together but not so much so that I could have envisioned this to be a problem. So what to do; disconnect the DAC interconnects at the back of the amp and the volume increases exponentially.I have no idea what the first two sentences mean, but it sounds like the input select function of the integrated amp may have a problem, and is shorting the inputs from the two sources together.
