I get the feeling that some confusion has happened over the circuit being positive earth.
Those transistor voltages have been measured with the meter negative on the battery negative.
This will include the voltages across the decoupling components leading to confusion.
Can the measurements be done again with one of the meter leads on the positive battery terminal.
We also need to establish if this set is not one of the odd ones with decoupling components in both power rails.
