There should be a small voltage at the base of the transistor. Because of tolerances of the individual components, the reading will be different for every amp.

My point was that the 15 volts is a typo. In fact one schematic that I have looked at lists .15 volts there. Maybe the decimal got wiped out at some point along the line.
