Hi all
The above mentioned amp is coming on but there is no output. Anybody has any schematics for this or any idea where to start with.

Do you have rail-rail oscillation on the output transistors?
What's the DC voltage on the power supply pins of the op-amp near the RCA jacks?

No there are no oscillations.Do you have rail-rail oscillation on the output transistors?

Op amps have +15 and -15v.
If you drive audio into the amp, does it reach the two 100uF caps near the 5532 op-amps in the class D drive section?
Yes. After I change two 393 ic I got the audio back.If you drive audio into the amp, does it reach the two 100uF caps near the 5532 op-amps in the class D drive section?
