Classical audio power amplifier with IT and OT transformer

The circuit is devote to the radio receiver in which sound ( the gear ) is weak. With the help of this tool , which initially sounds as if far to be clearly audible. Power amplifier does not require much  electrical current source , because all components are not up to over 1 Mega . But the result was incredible because it can enhance the power of  catching the wave signal.

Troubleshooting :
Wether transistors placement is correct ?
Placement Elco ?
Check are cable .

If all components have benn checked , and the damaged has been replaced . Then try , turn the potentiometer slowly and listen to how the sound output by the speaker.
