OK, your EB volages on both transistor pairs, Esecially on q15-17, are screwed up big time. Should be 0.5 to o.7 V and you have almost 5V.
Strange. As if your speaker shorts the output.
Hows the idle current?
When measuring voltages, idle or with signal? you do realize with no signal this amp cannot tell the phones from speakers unless..the dc cap is reversed, for example.
Have you set the idle?
