Default fuse blow

Please help it is connect everything like in schematics but when attach power supply, fuse get blow..is it schematic correct?



I found already one mistake:
Base of Q15 is not connected to Base Q16. Instead base Q15 is just connected to collector of Q15.
Base of Q16 is connected like in the picture (R29, R30) but not to Base Q15.

a tip for troubleshooting, you can't just isolate the Outputs and leave the Inputs connected like this:
