This is AN 948 circuit with modifications suggested by our group members as understood by me. I want to know whether they are correct?
1) Removed resistor from base of Q4 made direct connection.
2) Removed inductor from speaker output.
3) Added R14 ( 680 ohm same as R10) to base of Q6.
4) Added C8, C9 & C10. Kindly suggest values.
5) Added zener diode & diode as suggested.
Suggest zener diode value. The other diode i think is 1N4148.
Anybody built this circuit then let us have his experience about the circuit & any other modifications.
