Using the diode test on most DMMs gives the value of this voltage drop. Most Si devices, when reading forward across a junction, show about .6 -.69 volts.
A 1959 car radio I worked on recently had a (good) Delco DS-501 transistor for the output. Anyway, it measured much less and inconsistently on my Fluke, like Tom says.
