but I am guessing that these are really very good especially when you work out the formula for power the speakers see. I don't remember it now, but maybe others can chime in. There is a long thread on AK in the solid state forum , DC offset and you. Norm

In engineering schools there was a classic anecdote about "close enough". I think these measurements qualify.
At DC:
(P = watts, V = volts, R = ohms)
P = V^2 / R
R = 8 (typical)
V = 1.2 * 10^-3
V^2 = 1.44 * 10^-6
P = V^2 / R = 1.44 * 10^-6 / 8 = 0.18 * 10^-6 = about 1/5 of a microwatt
That will cause negligible voice coil heating and virtually zero deflection of the voice coil in the gap. Nothing to worry about.
Those readings are fine.
