hi all
i have been working on this project from 2 weeks.it worked nice.
it is really worth making circuit.

there 2 types of circuit.
1.it uses 600:600 center tapped transformer

2.this uses combination of resistors and capacitors for audio processing

now the problem is in my place this center tapped transformer is not available.so i went for resistor based circuit.it worked but the in/out going sound levels r very low.so is it possible for any improvement in this ckt.
is amplification of sound levels  possible?

can u modify the circuit for better performance.
thanks
