In the circuit you previously found that there were two 68 ohm resistors connected to the 12k resistors. The other end of those 68 ohm resistors is connected to the emitters of two SMD transistors. What is the amplitude of the signal on the base of those transistors?
Are the muting transistors still out of the circuit?

With all the transistors in the circuit, I have signal with 0,1V amplitude on the 68 ohm resistor and transistor connected to it.
Now I removed the muting transistors and the one transistor which allowed the amp to produce low volume audio.I have proper output on speaker terminals: 20V amplitude of sine. 2V on the transistors, which is connected to 68 ohms resistor, base.
