In the interest of clarification, I have added some
information to the schematic of the tape deck headphone
amp that I'm having problems with.
Some circuit paths are now labeled:

As always, the points at which voltage readings are
marked with a star are NOT producing the voltage
indicated. The +7V location is measuring 131mV instead.
The other two points where a star is indicated are
measuring between 20mV and 30mV (fluctuating slightly).
I am starting to think that a circuit OUTSIDE of this
circuit might be at fault, because NOTHING inside of this
circuit seems to be faulty...but the darn thing still
WILL NOT work.
Have you followed the recommended procedure for debugging direct-coupled
circuits like this?
Step 1 - remove all transistors and check them for shorts and opens out of
the circuit. An ohmeter usually suffices.
