Hifi Power supply unit problem

Hello
i do have a hifi amplifier

two compoennet is geting hot very fast, as soon as i start the amplifier

One transistor had failed
I changed it , but as soon you start the power , it is getting verry hot

on the schema it is the Q5 ans also R10 is getting hot

Any idee , i did have problem to understand
R16 ,D5 look ok
i did have 15volt on U1 pin 15
on my bord R42,R43 and Q7 is missing or shorted somehow
