Complaint is speaker wires shorted and the amp stopped playing.
Outputs are fine. getting -18.8v on adj pin of lm337 and 18.8v on lm317.

Thank you,

closest I have.
Thank you very much sir. I removed all the opamps and the voltage came back on +ve pin showing 20v and -ve pin showing -20v. But as soon as i replace one opamp both +ve and -ve pins of opamps having only negative voltage. -15v on negative pin and -11v on positive pin.
R41 is with in tolerance. But I had replaced D3 before because it was bad. I replaced it with 1n4007 instead 1n4003.Is R41 within tolerance?
