You are ABSOLUTELY CORRECT.  I took another good, hard look at the
service manual schematic (very fuzzy), and the base voltage of Q208 is
indeed +5.8V.

How did you deduce this?

I'm not sure about the 12K resistor across Q205's base-emitter.  I
will take a voltage measurement across that resistor and post it here.
