Bryon, 1.0 and 0.7 volts ac should certainly not be present at those points in the absence of signal, but I'm wondering if those readings might be due to meter inaccuracy.
Is the +/- 0.5 volt tolerance really the meter's specified accuracy, or is it the resolution of the measurement, in which case the accuracy could be and probably is worse than 0.5, and might account for the entire 1.0 volt reading?
What reading do you get if you touch the two leads of the meter to two different points on the chassis? Perhaps the meter is responding to emi being picked up by the leads.
Also, were you measuring at rca connectors, or xlr connectors?
If rca, did you connect the return lead of the meter directly to the ground sleeve of the rca jack being measured, or to some other presumed ground point, such as chassis?
If xlr, did you measure directly between pin 2 and pin 1, and pin 3 and pin 1, or was the return lead of the meter connected to some presumed ground point other than pin 1?
Best regards,
