hi norazmi the amp now is cool as cold can be it only gets slightly warm after like 20mins
ferrite core gets warm but managable. ferrite core is 3mm gap t-130-26 30turns
voltage is +/-36vlts .
i added 470ohms resistor in series with r6 and also i added 470ohms resistor in series with r7 so the total resistance r7 is 690ohms and r6 is 690 ohms .
i am using smps i posted in the post no #181

the surprising thing is that the amp is clear , silent (despite of using smps power supply) and has power all the glory goes to GOD almighty . thanks norazmi for all the help may the almighty GOD bless this forum and all the members . thanks guys i will upload photos .
