The output of my GEMINI GVX-SUB18P is weak and distorted. Also I measured the Voltages Ubase and Uemitter on the output transistors and both are the same: 0.40 Volt DC
Measuring that voltage wont tell you a lot of information. You need to see signals in an audio circuit and those transistors could be MOSFET and or they cannot be tested while in circuit.
