I Thank you for your reply.
Votages around Q1 are: Collector= 8V, Base= 1.1V Emmiter approx 0V.
Yes, I have an oscilloscope, and the circuit is not oscillating.
I cross checked the windings identifications with the transformer datasheet and they are as they should.

Those voltages indicate Q1 being faulty or damaged. This is where it gets messy. If Q1 started off being good and there is another fault that prevents oscillation, Q1 will sink about 100mA continuously, causing it to overheat and fail. Now you have 2 faults.
I suggest replacing Q1. Check or replace Q2, also check R5 in circuit.
Power it up gradually increasing the voltage while monitoring the current draw.
When the current gets up to about 100mA the voltage drop(0.6V) across R5 starts to turn Q2 on which shunts current away from the Base of Q1, preventing Q1's Collector current from rising further.
Also monitor the Collector of Q1 for oscillation in case of it deciding to work.
